  [CUDA][HIP] Support CUID in new driver (#122859)

CUID is needed by CUDA/HIP for supporting accessing static device
variables in host function.

Currently CUID is only supported by the old driver for CUDA/HIP. The new
driver does not support it, which causes CUDA/HIP programs using static
device variables in host functions to fail with the new driver for
CUDA/HIP.

This patch refactors the CUID support in the old driver so that CUID is
supported by both the old and the new drivers for CUDA/HIP.
