D3D12: Fix swapchains after 921fb5e1cef

Browse Source 
The Swapchain::Configure was changed to not require an initial usage
anymore. Previously the code was doing a transition to this usage
causing the code to now transition to <uninitialized data> usage.
Fix this by deleting code. Also make TextureD3D12 responsible for the
transition to PRESENT.
