Philip Withnall 0910e2f6ad girepository: Drop outdated/unused GIInfoType member 
It was deprecated since before libgirepository was moved into this
repository. Take the opportunity now to remove it entirely, as it’s a
bit confusing to have it in the public API.

This should not affect the binary typelib format, as it still has its
`BLOB_TYPE_INVALID_0` member, and that will remain in place until the
binary format next breaks compatibility (no plans to do that).

This is an API break in libgirepository, but since it’s not been in a
stable release yet, that’s fine.

Signed-off-by: Philip Withnall <pwithnall@gnome.org>
