Split out CreateCast into src/backend/catalog/pg_cast.c
This catalog-handling code was previously together with the rest of
CastCreate() in src/backend/commands/functioncmds.c. A future patch
will need a way to add casts internally, so this will be useful to have
separate.
Also, move the nearby get_cast_oid() function from functioncmds.c to
lsyscache.c, which seems a more natural place for it.
