Support T2T copies between formats that have only difference on srgb-ness

In previous T2T copy, Dawn requires textures have the same formats. But
Vulkan/Metal/D3D12 have ability to copy between "compatible" formats textures.

Metal has the most restrict rules without setting interpreter flags when creating
textures. It defines "compatible" texture formats to the formats that only have
difference on srgb-ness.

This CL follow Metal's rule and release the validations for T2T copies. It supports
T2T copy between "compatible" texture format textures.
