intel oneapi classic bootstrapping (#31285)
The `intel` compiler at versions > 20 is provided by the `intel-oneapi-compilers-classic` package (a thin wrapper around the `intel-oneapi-compilers` package), and the `oneapi` compiler is provided by the `intel-oneapi-compilers` package. Prior to this work, neither of these compilers could be bootstrapped by Spack as part of an install with `install_missing_compilers: True`. Changes made to make these two packages bootstrappable: 1. The `intel-oneapi-compilers-classic` package includes a bin directory and symlinks to the compiler executables, not just logical pointers in Spack. 2. Spack can look for bootstrapped compilers in directories other than `$prefix/bin`, defined on a per-package basis 3. `intel-oneapi-compilers` specifies a non-default search directory for the compiler executables. 4. The `spack.compilers` module now can make more advanced associations between packages and compilers, not just simple name translations 5. Spack support for lmod hierarchies accounts for differences between package names and the associated compiler names for `intel-oneapi-compilers/oneapi`, `intel-oneapi-compilers-classic/intel@20:`, `llvm+clang/clang`, and `llvm-amdgpu/rocmcc`. - [x] full end-to-end testing - [x] add unit tests
