This PR fixes several issues I noticed while trying to get Spack working on Apple M1.
- [x] `build_environment.py` attempts to add `spec['foo'].libs` and `spec['foo'].headers` to our compiler wrappers for all dependencies using a try-except that ignores `NoLibrariesError` and `NoHeadersError` respectively. However, The `libs` and `headers` attributes of the Python package were erroneously using `RuntimeError` instead.
- [x] `spack external find python` (used during bootstrapping) currently has no way to determine whether or not an installation is `+shared`, so previously we would only search for static Python libs. However, most distributions including XCode/Conda/Intel ship shared Python libs. I updated `libs` to search for both shared and static (order based on variant) as a fallback.
- [x] The `headers` attribute was recursively searching in `prefix.include` for `pyconfig.h`, but this could lead to non-deterministic behavior if multiple versions of Python are installed and `pyconfig.h` files exist in multiple `<prefix>/include/pythonX.Y` locations. It's safer to search in `sysconfig.get_path('include')` instead.
- [x] The Python installation that comes with XCode is broken, and `sysconfig.get_paths` is hard-coded to return specific directories. This meant that our logic for `platlib`/`purelib`/`include` where we replace `platbase`/`base`/`installed_base` with `prefix` wasn't working and the `mkdirp` in `setup_dependent_package` was trying to create a directory in root, giving permissions issues. Even if you commented out those `mkdirp` calls, Spack would add the wrong directories to `PYTHONPATH`. Added a fallback hard-coded to `lib/pythonX.Y/site-packages` if sysconfig is broken (this is what distutils always did).

This PR supports the creation of securely signed binaries built from spack
develop as well as release branches and tags. Specifically:
- remove internal pr mirror url generation logic in favor of buildcache destination
on command line
- with a single mirror url specified in the spack.yaml, this makes it clearer where
binaries from various pipelines are pushed
- designate some tags as reserved: ['public', 'protected', 'notary']
- these tags are stripped from all jobs by default and provisioned internally
based on pipeline type
- update gitlab ci yaml to include pipelines on more protected branches than just
develop (so include releases and tags)
- binaries from all protected pipelines are pushed into mirrors including the
branch name so releases, tags, and develop binaries are kept separate
- update rebuild jobs running on protected pipelines to run on special runners
provisioned with an intermediate signing key
- protected rebuild jobs no longer use "SPACK_SIGNING_KEY" env var to
obtain signing key (in fact, final signing key is nowhere available to rebuild jobs)
- these intermediate signatures are verified at the end of each pipeline by a new
signing job to ensure binaries were produced by a protected pipeline
- optionallly schedule a signing/notary job at the end of the pipeline to sign all
packges in the mirror
- add signing-job-attributes to gitlab-ci section of spack environment to allow
configuration
- signing job runs on special runner (separate from protected rebuild runners)
provisioned with public intermediate key and secret signing key

Old concrete specs were slipping through in `_assign_hash`, and `package_hash` was
attempting to recompute a package hash when we could not know the package a time
of concretization.
Part of this was that the logic for `_assign_hash` was hard to understand -- it was
called twice from `_finalize_concretization` and had special cases for both args it
was called with. It's much easier to understand the logic here if we just inline it.
- [x] Get rid of `_assign_hash` and just integrate it with `_finalize_concretization`
- [x] Don't call `_package_hash` at all for already-concrete specs.
- [x] Add regression test.

This PR introduces a new build cache layout and package format, with improvements for
both efficiency and security.
## Old Format
Currently a binary package consists of a `spec.json` file at the root and a `.spack` file,
which is a `tar` archive containing a copy of the `spec.json` format, possibly a detached
signature (`.asc`) file, and a tar-gzip compressed archive containing the install tree.
```
build_cache/
# metadata (for indexing)
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json
<arch>/
<compiler>/
<name>-<ver>/
# tar archive
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spack
# tar archive contents:
# metadata (contains sha256 of internal .tar.gz)
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json
# signature
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json.asc
# tar.gz-compressed prefix
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.tar.gz
```
After this change, the nesting has been removed so that the `.spack` file is the
compressed archive of the install tree. Now signed binary packages, will take the
form of a clearsigned `spec.json` file (a `spec.json.sig`) at the root, while unsigned
binary packages will contain a `spec.json` at the root.
## New Format
```
build_cache/
# metadata (for indexing, contains sha256 of .spack file)
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json
# clearsigned spec.json metadata
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spec.json.sig
<arch>/
<compiler>/
<name>-<ver>/
# tar.gz-compressed prefix (may support more compression formats later)
<arch>-<compiler>-<name>-<ver>-24zvipcqgg2wyjpvdq2ajy5jnm564hen.spack
```
## Benefits
The major benefit of this change is that the signatures on binary packages can be
verified without:
1. Having to download the tarball, or
2. having to extract an unknown tarball.
(1) is an improvement in efficiency; (2) is a security fix: we now ensure that we trust the
binary before we try to run it through `tar`, which avoids potential attacks.
## Backward compatibility
Also after this change, spack should still be able to handle the previous buildcache
structure and binary mirrors with mixed layouts.

This PR builds on #28392 by adding a convenience command to create a local mirror that can be used to bootstrap Spack. This is to overcome the inconvenience in setting up this mirror manually, which has been reported when trying to setup Spack on air-gapped systems.
Using this PR the user can create a bootstrapping mirror, on a machine with internet access, by:
% spack bootstrap mirror --binary-packages /opt/bootstrap
==> Adding "clingo-bootstrap@spack+python %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
==> Adding "gnupg@2.3: %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
==> Adding "patchelf@0.13.1:0.13.99 %apple-clang target=x86_64" and dependencies to the mirror at /opt/bootstrap/local-mirror
==> Adding binary packages from "https://github.com/alalazo/spack-bootstrap-mirrors/releases/download/v0.1-rc.2/bootstrap-buildcache.tar.gz" to the mirror at /opt/bootstrap/local-mirror
To register the mirror on the platform where it's supposed to be used run the following command(s):
% spack bootstrap add --trust local-sources /opt/bootstrap/metadata/sources
% spack bootstrap add --trust local-binaries /opt/bootstrap/metadata/binaries
The mirror has to be moved over to the air-gapped system, and registered using the commands shown at prompt. The command has options to:
1. Add pre-built binaries downloaded from Github (default is not to add them)
2. Add development dependencies for Spack (currently the Python packages needed to use spack style)
* bootstrap: refactor bootstrap.yaml to move sources metadata out
* bootstrap: allow adding/removing custom bootstrapping sources
This operation can be performed from the command line since
new subcommands have been added to `spack bootstrap`
* Add --trust argument to spack bootstrap add
* Add a command to generate a local mirror for bootstrapping
* Add a unit test for mirror creation

Currently, environments can either be concretized fully together or fully separately. This works well for users who create environments for interoperable software and can use `concretizer:unify:true`. It does not allow environments with conflicting software to be concretized for maximal interoperability.
The primary use-case for this is facilities providing system software. Facilities provide multiple MPI implementations, but all software built against a given MPI ought to be interoperable.
This PR adds a concretization option `concretizer:unify:when_possible`. When this option is used, Spack will concretize specs in the environment separately, but will optimize for minimal differences in overlapping packages.
* Add a level of indirection to root specs
This commit introduce the "literal" atom, which comes with
a few different "arities". The unary "literal" contains an
integer that id the ID of a spec literal. Other "literals"
contain information on the requests made by literal ID. For
instance zlib@1.2.11 generates the following facts:
literal(0,"root","zlib").
literal(0,"node","zlib").
literal(0,"node_version_satisfies","zlib","1.2.11").
This should help with solving large environments "together
where possible" since later literals can be now solved
together in batches.
* Add a mechanism to relax the number of literals being solved
* Modify spack solve to display the new criteria
Since the new criteria is above all the build criteria,
we need to modify the way we display the output.
Originally done by Greg in #27964 and cherry-picked
to this branch by the co-author of the commit.

* Inject reusable specs into the solve
Instead of coupling the PyclingoDriver() object with
spack.config, inject the concrete specs that can be
reused.
A method level function takes care of reading from
the store and the buildcache.
* spack solve: show output of multi-rounds
* add tests for best-effort coconcretization
* Enforce having at least a literal being solved
