[OpenACC] Implement `loop` restrictions on `for` loops. (#115370)
OpenACC restricts the contents of a 'for' loop affected by a 'loop'
construct without a 'seq'. The loop variable must be integer, pointer,
or random-access-iterator, it must monotonically increase/decrease, and
the trip count must be computable at runtime before the function.
This patch tries to implement some of these limitations to the best of
our ability, though it causes us to be perhaps overly restrictive at the
moment. I expect we'll revisit some of these rules/add additional
supported forms of loop-variable and 'monotonically increasing' here,
but the currently enforced rules are heavily inspired by the OMP
implementation here.

[OpenACC] Implement 'private' clause sema for loop constructs
This clause works identically as far as Sema is concerned, to the
'private' clause on compute constructs, so this simply adds tests and
unblocks the ASTNode generation and Sema checking when used on loop
clauses.
