don't include hdf5.h or use HDF5 typedefs in public header files (bug #43180)
* oct-hdf5-types.h: Rename from oct-hdf5-id.h.
* oct-hdf5-types.cc: Rename from oct-hdf5-id.cc.
* libinterp/corefcn/module.mk: Update.
* oct-hdf5-types.h (octave_hdf5_err): New typedef.
* oct-hdf5-types.h, oct-hdf5-types.cc (check_hdf5_types): Rename from
check_hdf5_id_type. Also check size of herr_t.
* load-save.cc: Include oct-hdf5.h.
* ls-hdf5.cc: Include oct-hdf5.h instead of oct-hdf5-id.h.
Define hdf5_fstreambase functions that require HDF5 types here instead
of in ls-hdf5.h.
* ls-hdf5.h, ls-hdf5.cc: Use octave types in public interfaces.
* ls-hdf5.h, ov-base.h: Include oct-hdf5-types.h instead of oct-hdf5.h.
* oct-hdf5.h: Include oct-hdf5-types.h. Define H5T_NATIVE_IDX here.
* ls-hdf5.h: Not here.
