  [Flang][MLIR][OpenMP] Host-evaluation of omp.loop bounds (#133908)

This patch updates Flang lowering and kernel flags identification in
MLIR so that loop bounds on `target teams loop` constructs are evaluated
on the host, making the trip count available to the corresponding
`__tgt_target_kernel` call emitted for the target region.

This is necessary in order to properly execute these constructs as
`target teams distribute parallel do`.
