Log Message:
support ref intent on gpuized forall w/ AMD (#25647)
This PR extends the work from #25594 so that ref intent scalars will
work with forall loops on AMD GPUs (the prior PR got it to work for
NVIDIA).
Since AMD GPUs (or at least the ones we're using today) don't have
universal addressing we need to convert the host pointer to the ref
intent'd parameter into a "device pointer" before it can be used by the
device. This PR performs this step.
