Support linking to a static pre-built HDF5

Why:

- So that you don't have to built HDF5 from source
- To statically linked against an exact version of HDF5

How to test:

- In both homebrew/apt, there's `.a` libs included
- There's `hdf5-static` package in conda-forge which is now built on all platforms, plus openmpi/mpich flavors of it on linux/macos
- In official .msi windows builds, maybe there's static libs too, needs checking
