Move Metal drawable presentation from MTLCommandBuffer to MTLDrawable.

Update MVKPresentableSwapchainImage::presentCAMetalDrawable() to create a
MTLCommandBuffer scheduled-handler and present the MTLDrawable from there.

According to Apple, it is more performant to call MTLDrawable present from within a
MTLCommandBuffer scheduled-handler than it is to call MTLCommandBuffer presentDrawable:.

Pass presentation timing info as a struct to simplify calls.
