Implement basic metadata support for QMediaPlayer

Unfortunately, GstDiscover has a crappy API that doesn't
allow us to retrieve the data from a running decoder
session (we'd be forced to create a separate decoder session
just to get the data). So let's do things more manually
and parse the topology data from decodebin ourselves.
