Build HDF5 libraries for Python packages

Builds HDF5 libraries (version 1.12.2) so that they can be used for linking in various Python packages. This attempts to match the build process used by cibuildwheel:

• For manylinux_x86_64, we create a Docker image based on quay.io/pypa/manylinux2014_x86_64. These have HDF5 and friends installed in a standard location and should directly work with find_package(). One of the versioned images should be used with the CIBW_MANYLINUX_X86_64_IMAGE option.
• For musllinux_x86_64, we create a Docker image based on quay.io/pypa/musllinux_1_1_x86_64. These have HDF5 and friends installed in a standard location and should directly work with find_package(). One of the versioned images should be used with the CIBW_MUSLLINUX_X86_64_IMAGE option.
• For macosx_x86_64, we build binaries using the macosx-11 runner. The resulting tarball should be unpacked to the installed directory, which can then be set to CMAKE_INSTALL_PREFIX for find_package().
• For macosx_arm64, we build binaries manually on an M2 with MacOSX 13 that I have lying around. (Not ideal, but until GitHub offers an M1/2 runner, it's the best I can do.) The resulting tarball should be unpacked to the installed directory, which can then be set to CMAKE_INSTALL_PREFIX for find_package().
• For windows_x86_64, we build binaries using the windows-2019 runner. The resulting tarball should be unpacked to the installed directory, which can then be set to CMAKE_INSTALL_PREFIX for find_package(). Note that MSVC builds should also define the H5_BUILT_AS_DYNAMIC_LIB macro.
