  [flang] Add a pass to get OpenACC device ptr for CUDA kernel (#212299)

When a CUDA kernel is launched inside an OpenACC data region, it does
not properly get the device pointers and instead uses host data. This PR
adds a pass to get the device pointers set up by the OpenACC data
construct and pass them explicitly to the CUDA kernel.

Note: A possibly non-contiguous array argument is currently not supported. This pass will skip these cases.
