[misc/player] Introduce output ability to announce supported formats

Browse Source 
Also introduce default output format and selected device format, should the
user want another format.

As part of this, change enum player_format in player.h to enum media_format in
misc.h so that it is akin to struct media_quality.

Modify json API to support this.
