Don't filter out unsupported/forced tracks

[MGaetan89]

Pull request

Description

This PR fixes the selection of alternative audio/text/video tracks, when some tracks have been filtered out. When selecting an other track, Media3 checks that the provided group is a known one, thus we keep filter out some tracks.

Changes made

• Remove filtering on audio/text/video tracks
• Update demo apps to disable unsupported tracks
• Update tests to include unsupported tracks

• APIs have been properly documented (if relevant).
