Implement `seq_cst` RC11/ptx6.0 memory consistency for CUDA backend.

See https://dl.acm.org/doi/pdf/10.1145/3297858.3304043 and
https://docs.nvidia.com/cuda/parallel-thread-execution/index.html#memory-consistency-model
for full details. Requires sm_70 or above. With this PR there is now a
complete mapping between SYCL memory consistency model capabilities and
the official CUDA model, fully exploiting CUDA capabilities when
possible on supported arches.

This makes the SYCL-CTS atomic_ref tests fully pass for sm_70 on the
cuda backend.

Fixes intel#11208

Depends on intel#12907

Tests UR PR oneapi-src/unified-runtime#1447 that
only reports support for UR command-buffers on ROCm 5.5.1 and later to
work around HIP driver bugs related to HIP-Graph in earlier version.

This requirement is also explicitly mentioned in the design doc.
