WMF: fixed unresolved topologies when using the custom MediaSink.

When using our custom MediaSink with RGB formats, Media Foundation fails
sometimes to resolve the topology. Inserting ourselves a ColorConverter
transform in the topology resolves the problem.

The ColorConverter transform cannot handle dynamic frame size changes
(this can happen with H264 videos for example) so we also need to insert a
Resizer transform to handle transparently frame size changes.
