winrt: Add media playback service

Browse Source 
This introduces a MediaPlayer service based on the MFEngineEx API. Only
scene graph video rendering is supported at this time. The video renderer
control is abstracted in order to provide a base for future video nodes
which do not source their content from the MF engine.

[ChangeLog] Media player support was added to the winrt backend.
