DirectShow: use the EVR in the renderer control.

As for the window control, the existing code from the WMF plugin has
been refactored out and is now shared for both plugins.
This enables HW-accelerated video decoding in QML, QGraphicsVideoItem
and custom QAbstractVideoSurfaces (Angle is required).
