  [OpenACC] Implement tile/collapse lowering (#138576)

These two ended up being pretty similar in frontend implementation, and
fairly trivial when doing lowering. The collapse clause jsut results in
a normal device_type style attribute with some mild additional
complexity, and 'tile' just uses the current infrastructure for 'with
segments'.
