  [GISel] Restrict G_BSWAP to multiples of 16 bits. (#70245)

This is consistent with the IR verifier and SelectionDAG's getNode.

Update tests accordingly. I tried to keep some coverage of non-pow2 when
possible. X86 didn't like a G_UNMERGE_VALUES from s48 to 3 s16 that got
created when I tried s48.
