feat(YouTube): Add Exit fullscreen mode patch

[LisoUseInAIKyrios]

Adds an option to exit fullscreen mode at the end of a video.

Works well with Open Shorts in regular player and the fullscreen player.

It was easier than I thought 😁

Very. I spent longer typing out all the boiler plate code and resources than making the actual patch.

Continuing the idea, it would be cool to add the ability not to exit full-screen mode when returning to the player, for example, after unlocking the screen.
If I remember correctly, Vanced had this feature.

LOL...you can save the previous player state in a field and use this to send a onClick() event to the same button again...once the player quit from fullscreen.

...but, honestly, idk if this approach will increase the patch complexity too much.

[LisoUseInAIKyrios]

It might be easier, and probably more reliable, to instead patch the logic that switches from fullscreen to portrait when the app is resumed.

I once used a similar function in another fork, but there was a bug in PiP mode on some firmwares (in my case, MIUI), although no such bug was detected in others.

@LisoUseInAIKyrios yeah, it is, but if you want to speed up the patch development...xD

This feature is currently available on 19.50.40 and rvp v.5.8.1 for me and some users, maybe some a/b flag (this?) has become active for some accounts, maybe for all. Can you confirm this as well?

Maybe somehow related to problems with PiP #4287
because same issue was there for me
#4223 (comment)
this patch forced same a/b flag
