  [flang][cuda] Perform scalar assignment of c_devptr inlined (#123407)

Because `c_devptr` has a `c_ptr` field, any assignment were done via the
Assign runtime function. This leads to stack overflow on the device and
taking too much memory. As we know the c_devptr can be directly copied
on assignment, make it a special case.
