…torch#12654) Summary: Built flash attention compute shader for Vulkan backend delegate. The current implementation only supports buffer storage and is not fully optimized, but is functional. This shader should speed up the SDPA process in the attention block of transformer inferencing as the previous implementation used many i/o operations. The implementation includes proper multi-query attention support for models like LLaMA, uses tiled block processing to reduce memory usage, and replaces multiple separate operations (matmul, softmax, masking) with a single efficient compute shader.
