Adds a DBus message handler that plays a video via Qt

[nicomiguelino]

Description

• Qt (via QMediaPlayer) will replace VLC for playing videos.
• This might fix the black gap between active video assets.
  • Replacing OMX with VLC doesn't cut it, so I decided to resort to using Qt's media player.
• The changes might not work on older Pi devices. With that, the replacement will only be partial.

This PR doesn't seem to change the actual playback method tho. It only adds it to QT.

Also, this needs to be tested on Pi 3, Pi 4 and ideally others.
