texture_cache: Implement depth stencil texture swizzles

Browse Source 
Stop ignoring image swizzles on depth and stencil images.

This doesn't fix a known issue on Xenoblade Chronicles 2 where an OpenGL
texture changes swizzles twice before being used. A proper fix would be
having a small texture view cache for this like we do on Vulkan.
