metal : add GGML_OP_TOP_K_MASK (#31230)

• metal : add GGML_OP_TOP_K_MASK

Port the fused top-k mask from the CUDA backend: a grid-stride kernel fills the output with -inf, then one
threadgroup per row copies the mask values of the kept cells over it. Function constants drop the score,
blocks and extra paths that a given graph does not use.
