[PATCH V5 06/16] xfs: Promote xfs_extnum_t and xfs_aextnum_t to 64 and 32-bits respectively

A future commit will introduce a 64-bit on-disk data extent counter and a
32-bit on-disk attr extent counter. This commit promotes xfs_extnum_t and
xfs_aextnum_t to 64 and 32-bits in order to correctly handle in-core versions
of these quantities.
