WMF and GStreamer: fixed incorrect frame startTime and endTime.

Browse Source 
The QVideoFrame documentation explicitly says that the time is in
microseconds, however the GStreamer backend was setting the time in
milliseconds and the WMF backend in 100-nanosecond units.
With WMF, the time was missing from the QVideoFrame when presenting it to
the video surface.

Task-number: QTBUG-31731
