Move bitmap_hash and bitmap_match to bitmapset.c.

Browse Source 
The closely-related function bms_hash_value is already defined in that
file, and this change means that hashfn.c no longer needs to depend on
nodes/bitmapset.h. That gets us closer to allowing use of the hash
functions in hashfn.c in frontend code.

Patch by me, reviewed by Suraj Kharage and Mark Dilger.
