Fix issue of reseting CAMetalDrawable and MTLTexture of peer swapchain images.

Add MVKPresentableSwapchainImage and MVKPeerSwapchainImage subclasses to
MVKSwapchainImage, with MVKPresentableSwapchainImage instances created inside
swapchain, and MVKPeerSwapchainImage instances created using vkCreateImage().
MVKPeerSwapchainImage retrieve and share CAMetalDrawable from corresponding
MVKPresentableSwapchainImage.
