* helper function for selecting the optimal coopmat mnk size

* add int8 definitions
* packing vulkan int8/int32, quantize vulkan
* vulkan dequantize
* requantize vulkan

vkimagemat was originally used as a mat storage in the hope of improving performance on old adreno gpus, but in fact it is slower than the cpu in most cases and is no longer suitable for the latest adreno architecture and large shapes

* check image fp16

* destroy_gpu_instance() will internally ensure that all vulkan devices are idle before proceeding with destruction.

* vulkan-driver-loader.md
* static vulkan on apple

* enable VK_KHR_cooperative_matrix
* add khr cm shader
* update glslang
* print matrix info

* fix vulkan validation error, prefer VK_KHR_buffer_device_address over VK_EXT_buffer_device_address

* enable validation extension features

* Add some extension capability for vma

* enable VK_KHR_portability_subset extension if device support it
