MediaCategoryViewController: Last Played Playlist Media Indicator

The following feature was requested in #1760 (closed)

I have added an indicator to the MediaCategoryViewController for the last played playlist and its last played media. it is immediately updated based on the playback state. When the playback is active, it is hidden, and when the playback is stopped, it is shown.

The indicator can detect the playlist and its media in the following scenarios:

• When playing a single media from a playlist.
• When playing an entire playlist.
• When switching from playing an entire playlist to a single media from the playlist, and vice versa.

All of these cases are detected using the tap select action and long press gestures actions (play, play next in queue, and append to queue) when the queue is empty.

For MovieCollectionViewCell, added a label called groupLastPlayed for indicating the playlist in Grid mode, and for a single media inside the playlist Grid mode is not an option.

changed title from MediaCategoryViewController: Last Played Playlist Indicator to MediaCategoryViewController: Last Played Playlist Media Indicator

changed the description

Two additional remarks:

1. Regarding the changes you will have to make to the LastPlayedPlaylistModel and LastPlayedPlaylistMedia structs, we could maybe add them to an already existing file (perhaps the PlaylistModel one) to avoid the addition of such a small file.
2. You maybe forgot some commits, I couldn't manage to display the last played label on the proper media inside the last played playlist.

I fixed the newLabel bug and added the ability to correctly indicate the last played media for a given playlist in case the user added many different media from different playlists to the player queue.
