  [MLIR][NVVM] Support stmatrix intrinsics (#148377)

Add support for the `@llvm.nvvm.stmatrix` intrinsic series. These
correspond to PTX stmatrix operations, as documented in the [PTX ISA
reference](https://docs.nvidia.com/cuda/parallel-thread-execution/index.html#warp-level-matrix-store-instruction-stmatrix).
