vo_gpu/d3d11: add more usage flags to the swapchain images 

vo_gpu_next and libplacebo expect swapchain images to be able to be
blitted to, which for libplacebo on FL11_0 and up means they have to
have DXGI_USAGE_UNORDERED_ACCESS, since libplacebo uses a compute shader
to emulate certain kinds of blits. For libplacebo's benefit, set all
applicable usage flags on swapchain images.
