  -----------
  [CIR][CUDA] Add support for scoped NVVM atomic builtins (#210863)

Adds codegen support for the block and system-scoped NVVM atomic
builtins: add, and, or, xor, min, max, inc and dec.

These are lowered to the corresponding CIR `cir.atomic.fetch` operations
and subsequently lowered to LLVM `atomicrmw` instructions.
