ECP-SDK: fixup +hdf5 +cuda contraints (#33676)

Only enable the hdf5-vfd-gds package if it can compile.

- hdf5-vfd-gds needs cuda@11.7.1+ to be able to `find_library` for cuFile.
- Only enable hdf5-vfd-gds in the sdk if cuda@11.7.1+ is available.
  If an earlier version of cuda is being used, do not depend on the
  hdf5-vfd-gds package at all.
