  [OpenACC][CIR] Implement basic lowering for combined constructs (#139119)

Combined constructs are emitted a little oddly, in that they are the
first ones where there are two operations for a single construct. First,
the compute variant is emitted with 'combined(loop)', then the loop
operation is emitted with 'combined(<variant>)'. Each gets its own
normal terminator.

This patch does not yet implement clauses at all, since that is going to
require special attention to make sure we get the emitting of them
correct, since certain clauses go to different locations, and need their
insertion-points set correctly. So this patch sets it up so that we will
emit the 'not implemented' diagnostic for all clauses.
