vulkan: fix coopmat2 validation failures (ggml-org#11284)
mul mat and flash attention shaders were loading f32 types directly into A/B matrices, which happens to work but is technically invalid usage. For FA, we can load it as an Accumulator matrix and convert and this is not in the inner loop and is cheap enough. For mul mat, it's more efficient to do this conversion in a separate pass and have the input(s) be f16. coopmat2 requires SPIR-V 1.6 (related using to LocalSizeId). LocalSizeId requires maintenance4 be enabled, and SPIR-V 1.6 requires Vulkan 1.3.
