[flang][cuda] Do not produce data transfer in offloaded do concurrent (#147435)

If a `do concurrent` loop is offloaded then there should be no CUDA data
transfer in it. Update the semantic and lowering to take that into
account.

`AssignmentChecker` has to be put into a separate pass because the
checkers in `SemanticsVisitor` cannot have the same `Enter/Leave`
functions. The `DoForallChecker` already has `Eneter/Leave` functions
for the `DoConstruct`.
