Revert "d3d11: Add support for D3D11_USAGE_DYNAMIC"

This reverts commit ddd13fc7

Dynamic usage can reduce the number of copy per frame but make
things complicated and the benefit seems to not significant.
Also since we don't provide _map() method for the dynamic usage,
application cannot read buffers which make "last-sample" property
unusable in case of d3d11videosink.
