llama.cpp adds Vulkan Intel FA shader for improved LLM performance

The llama.cpp project has released an update (b12331) that introduces significant improvements for Intel GPUs using Vulkan. This update includes a customized FA shader specifically for prefill operations, enhancing performance and accuracy. Key enhancements involve support for m16n16k16/SIMD32, refined buffer access, and optimizations for handling various edge cases and large head dimensions. The changes also focus on managing shared local memory (SLM) usage within the 48 KiB limit for Intel FA kernels, ensuring better compatibility and stability across different Intel GPU architectures.
