If possible, we would like to share more code with wined3d instead of
copying wined3d_swapchain_set_fullscreen() to
d3d12_swapchain_SetFullscreenState().

This probably should go into d3d12_swapchain_init().

Coding style.

This introduces a memory leak. All objects in d3d12_swapchain
structure are leaked.
