Add quirk to avoid VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT on Adreno GPUs

Browse Source 
Adreno GPUs have significant performance penalties from usage of `VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT` which require disabling UBWC and on Turnip, forces linear tiling. As a result, it's been made an optional quirk which doesn't supply the flag in `VkImageCreateInfo` and logs a warning if a view with a different Vulkan format from the original image is created.
