* Vulkan: Implement VK_KHR_cooperative_matrix support in the matrix matrix multiplication shader * Improve performance with better q4_k and q5_k dequant and store unrolling * Add Vulkan MUL_MAT and MUL_MAT_ID accumulator precision selection * Rework mulmat shader selection and compilation logic, avoid compiling shaders that won't get used by device * Vulkan: Implement accumulator switch for specific mul mat mat shaders * Vulkan: Unroll more loops for more mul mat mat performance * Vulkan: Add VK_AMD_shader_core_properties2 support to read Compute Unit count for split_k logic * Disable coopmat support on AMD proprietary driver * Remove redundant checks * Add environment variable GGML_VK_DISABLE_COOPMAT to disable VK_KHR_cooperative_matrix support * Fix rebase typo * Fix coopmat2 MUL_MAT_ID pipeline selection
