This reverts commit b1edfde279.
Reason for revert: senorblanco@ is adding a WriteOnly flag which will
be more appropriate for this functionality.
Original change's description:
> Rename GLRTFBOIDIs0 to WrapsSwapchainSurface and use for Metal.
>
> This provides a way to indicate that a Metal RenderTarget, and in
> particular a RenderTargetProxy, is framebufferOnly, so it can be
> restricted to certain operations.
