  [OpenACC][CIR] Lower 'wait' clause for compute/data constructs (#137359)

The 'wait' clause is a bit complicated, and is laid out awkwardly in the
IR addative functions, so this patch has to do a little bit of work to
do that (mostly the 'devnum' work).

Otherwise, this is very similar to how num_gangs works, with the
additional complexity of the 'empty' wait being represented differently
as well, but this is similar to how 'async' and a few others work as
well.
