Subject: [PATCH] [CUDA] Bump  the latest supported CUDA version to 11.4.

This should reduce the amount of noise issued by clang for the recent-ish CUDA
versions.

Clang still does not support all the features offered by NVCC, but is expected
to handle CUDA headers and produce binaries for all GPUs supported by NVCC.
