Play from beggining on Apple TV

[semiligneous]

Describe the feature you'd like
The Apple TV no longer supports a "Play from beginning" button/feature, so that if an episode is half way through the user can easily start the episode from the start without having to skip backwards in 15s increments many, perhaps hundreds of times.

The feature/button should be accessible from the player interface (eg when you click the middle remote button) somewhere near to the subtitle/audio/nest-previous-episode buttons, as well as from the episode/movie info page where there is currently a "Play" button. Long pressing Play should play from beginning, or a second button to do that.

Additional context
Discussed here: #1471 - This used to exist and would make using the interface much easier, but didn't survive a recent code refactor.

I haven't looked into this at all but I believe the .injectCustomValues(startFromBeginning: true) doesn't exist anymore? Regardless, this isn't just a pure un-comment. I believe we need to figure out the logic again. If anyone wants to pick this up, please wait until after #1203.
