Rework how to set a video output surface

Setting a video output should not require QMediaService
anymore.

Reverse the logic, by making QAbstractVideoSurface the primary
interface. Use runtime method lookup to get a pointer to the
video surface from QVideoWidget/QGraphicsVideoItem.

QAbstractVideoSurface is now the primary interface for setting
up a video output. We will need to add some API there to allow for
windows/fullscreen rendering.

With this change, QVideoRendererControl/QVideoWindowControl can
also be retired as an abstraction layer in the longer term.
