Identify Windows support with tags (#35027)

All packages with explicit Windows support can be found with
`spack list --tags=windows`.

This also removes the documentation which explicitly lists
supported packages on Windows (which is currently out of date and
is now unnecessary with the added tags).

Note that if a package does not appear in this list, it *may*
still build on Windows, but it likely means that no explicit
attempt has been made to support it.

-Many Spack packages are not currently compatible with Windows, due to Unix
-dependencies or incompatible build tools like autoconf. Here are several
-packages known to work on Windows:
-
-* abseil-cpp
-* bzip2
-* clingo
-* cpuinfo
-* cmake
-* hdf5
-* glm
-* nasm
-* netlib-lapack (requires Intel Fortran)
-* ninja
-* openssl
-* perl
-* python
-* ruby
-* wrf
-* zlib
+Not all spack packages currently have Windows support. Some are inherently incompatible with the
+platform, and others simply have yet to be ported. To view the current set of packages with Windows
+support, the list command should be used via `spack list -t windows`. If there's a package you'd like
+to install on Windows but is not in that list, feel free to reach out to request the port or contribute
+the port yourself.
 
 .. note::
-   This is by no means a comprehensive list
