Migrate to androidx-media3 video player (#3857)

Behaviour is consistent with previous player except that:

- Swapping apps while a video is playing, and then returning to Tusky,
will keep the seek position in the video instead of returning to the
start
- The controls/media description can be shown by tapping anywhere, not
just on the video itself
- The media description is on-screen for the same duration as the player
controls (5 seconds here, 3 seconds in the previous code)
- The user has options to control the playback speed
- Rotating the device does not squash/stretch the video
- Show the media preview when playing audio-only files

Fixes #3329,
#3141,
#3126,
#2753,
#3508,
#3291
