[OpenACC] Implement 'modifier-list' sema/AST

OpenACC 3.3-NEXT has changed the way tags for copy, copyin, copyout, and
create clauses are specified, and end up adding a few extras, and
permits them as a list.  This patch encodes these as bitmask enum so
they can be stored succinctly, but still diagnose reasonably.
