feat: hide video title on fullscreen

[asifurrahaman754]

Issue #1677

feature added in appearrance -> player -> hide video title in fullscreen

It will hide the video title when the video is fullscreen and the option is enabled. Currently, this feature works for all videos, not for a category of videos

What about starting with if storage .. = true?

also adding optimization when switching off the feature (while our code runs billions of times, most features are switched on permanently.

We only need to switch off most features based on user input (So less code runs billions of times. most features are switched on permanently and allow to "set&forget" ) (even if this time it matters less: can only be tested through enabling the ImprovedTube icon on Youtube: drag & drop)

(this way the feedback when switching on/off the feature is automated in our script and including it with a shortcut was easy too)
(Didnt benchmark which is faster? - came up with this way when JS was still slower)
