  [flang][cuda] Perform inlined assignment when field is c_devptr (#124322)

When a field in a derived type is `c_devptr`, keep check if we can do a
memcpy instead of falling back to the runtime assignment.

Many internal CUDA Fortran derived type have a `c_devptr` field and this
would lead to stack overflow on the device if the assignment is
performed by the runtime function.
