Hdf5 package: build on Windows (#31141)

* Enable hdf5 build (including +mpi) on Windows
* This includes updates to hdf5 dependencies openssl (minor edit) and
  bzip2 (more-extensive edits)
* Add binary-based installation of msmpi (this is currently the only
  supported MPI implementation in Spack for Windows). Note that this
  does not install to the Spack-specified prefix. This implementation
  will be replaced with a source-based implementation
