D3D12: Recursive layer support
To avoid using the same color buffer both as a shader resource and as a
render target, recursive layers add a second render target and just play
ping-pong with them. Multisampling does not need this since rendering
happens into a MS buffer while shader access uses a separate, non-MS color
buffer.
