Jean-Yves Avenard d346b32eb9 Bug 1409664 - P11. Add GetTracksInfo method to all MediaDecoder instances. r=bryce
Summary:
Allows to build an array ot TrackInfo built from the mimetype provided. This will allow to create dummy decoder to check that if they are supported and how well the decoder will perform.

Depends on D1623
