HDF5 is too old for ITK in Windows

[KrisThielemans]

When using our own HDF5 and building ITK 5.2 (on Windows with CMake 3.22, but probably elsewhere not on Ubuntu 18.04 with CMake 3.17), we get an error that this HDF5 library is too old to enable backwards compatibility, and ITK suggests to let it use its own HDF5 version. For the SB, this means setting ITK_USE_SYSTEM_HDF5=OFF (defaults to ON to save some space/compilation time).

options:

1. hope that the user will know what to do (i.e. document it better)
2. we could try and be smart to catch this by doing some HDF5 version checking ourselves
3. upgrade our HDF5 library in the next release.
4. default ITK_USE_SYSTEM_HDF5=OFF

can't use ITK_USE_SYSTEM_HDF5=OFF due to InsightSoftwareConsortium/ITK#3315. We will need to upgrade our HDF5 version.
