  Log Message:
  -----------
  [mlir][acc] Added async to data clause operations. (#97307)

As long as the data clause operations are not tightly
"associated" with the compute/data operations (e.g.
they can be optimized as SSA producers and made block
arguments), the information about the original async()
clause should be attached to the data clause operations
to make it easier to generate proper runtime actions
for them. This change propagates the async() information
from the OpenACC data/compute constructs to the data clause
operations. This change also adds the CurrentDeviceIdResource
to guarantee proper ordering of the operations that read
and write the current device identifier.
