xfs: Move extent count limits to xfs_format.h

Source kernel commit: 3b0d9fd369ea48419ccb578e0bafa4c54df63ba6

Maximum values associated with extent counters i.e. Maximum extent length,
Maximum data extents and Maximum xattr extents are dictated by the on-disk
format. Hence move these definitions over to xfs_format.h.
