igl | vulkan | Fix deprecated PVRTC formats validation errors

Summary:
PVRTC formats are deprecated without replacement. This diff fixes some Vulkan validation errors.

> Both PVRTC1 and PVRTC2 are slower than standard image formats on PowerVR GPUs, and support will be removed from future hardware.
