Metal: deferred render command encoder creation. MTLRenderCommandEncoder creation will be deferred until a render pass ends. Commands will be stored into a back-end owned buffer during render pass. At the end of the render pass, those commands will be re-encoded into an actual MTLRenderCommandEncoder. Benefits: - Useful for future implementation of occlusion query buffer where it could be allocated right before the end of a render pass to be big enough to store all queries within the render pass. - It's possible to change load option (deferred clear) as long as there is no draw call issued yet. This is not implemented yet. - Possibility of commands' re-ordering.
