Enable the MediaPlayerPrivateWebM by default, which will disable the
MediaFormatPlayer path.
It will be enabled on all platforms supporting MEDIA_SOURCE

This allows to play WebM file with supported codecs on iOS.

Already covered by existing tests, the MediaPlayerPrivateWebM was already
enabled on automation.
