Previously this toggle was implemented only for the Metal backend, but a need for it was identified on Android as well. This change moves the implementation to the backend-agnostic command encoder recording so that it works for all backends. Fundamentally it's still doing the same thing, however: Swapping resolve targets that point at a non-zero mip level or layer with a temporary texture and then performing a copy once the render pass has ended.
