d3d11window: Clear cached buffer per new caps

Browse source 
d3d11window holds one buffer to redraw client area per resize event.

When the input format is being changed, this buffer should be cleared
to avoid mismatch beween newly configured shader/videoprocessor and
the format of previously cached buffer.
