[gnome-music/wip/jfelder/mpris-truly-unique-ids: 8/10] player: Define a current_song_index property for the playlist

[Jean Felder <jfelder src gnome org>]

commit 0f5a63bd4657ae407ddd074c447ab5510c81e5c4
Author: Jean Felder <jfelder src gnome org>

    player: Define a current_song_index property for the playlist
    
    Switch from a getter to a GObject property. This allows to have the
    equivalent of the current_song property.
    
    This property will be used by the player in the next commit to
    uniquify the list of songs returned to MPRIS.
