Thread: pgsql: Add some opfamily support functions to lsyscache.c

Add some opfamily support functions to lsyscache.c

Add get_opfamily_method() and get_opfamily_member_for_cmptype() in
lsyscache.c.  No callers yet, but we'll add some soon.  This is part
of generalizing some parts of the code away from having btree
hardcoded and use CompareType instead.
