HDF5: make much more robust across platforms

This addresses various real-world problems with HDF5 pkg-config, including

* hdf*.pc with package versions as part of the filename
* malformed hdf*.pc missing the commonly-used HDF5 HL module

---

Additionally, this refactors more complicated dependencies such as
HDF5 and OpenMPI. This may help us deduplicate internal dependency
code in the future.

HDF5 selftest: improve platform-agnostic test

ci: init demo github action for HDF5 framework

ci Actions: hold off on MSYS2 for now [skip ci]

hdf5: ensure C libraries always included

ci: mac hdf5--use clang+gfortran
