fix(NVCC): warning supression pragma fix for CUDA >= 11.5 (#851)

CUDA 11.5 deprecated (and CUDA 12.0 removed) diagnostic pragmas such as diag_suppress and diag_default.

Replacement pragmas were previxed with nv_, i.e. nv_diag_suppress

__NVCC_DIAG_PRAGMA_SUPPORT__ is defined if the prefixed versions are available.
