This PR enables cubemap array extension in compute shaders when supported by the platform. When used the shader must include cubemap_lib as it contains a fallback implementation when cubemap arrays aren't supported by the platform. NOTE: This extension is available in Core Vulkan and doesn't need to be enabled. Metal doesn't support cubemap arrays and would use the fallback.
