[Android] YT Improvements - Settings to remove distracting elements

[timchilds]

Description

We could improve the YT experience in Brave by giving users the option to remove "distracting" elements from the page. These could be enabled via a new settings group.

e.g.

• Comments
• Live chat
• Related videos
• etc

A couple of examples of other products doing this:

• https://piped.video/preferences (https://github.com/TeamPiped/Piped)
• https://unhook.app/ (chrome extension)
