Add ability to move extension specific menu options to a grouped subsection on an individual basis

[cnapolit]

Feature description

As extensions continue to be released, bloat within the game/main menus will become a greater issue. One potential solution is to allow the ability to move extension specific menu options into a grouped subsection:

// Current Behavior

game menu -> ExtensionOptionInMenu        -> SomeOptions...
          -> AnotherExtensionOptionInMenu -> SomeOptions...
          -> SomeExtensionOptionInMenu    -> SomeOptions...

// New Behavior with functionality enabled for 'AnotherExtensionOptionInMenu' & 'SomeExtensionInMenu'

game menu -> ExtensionOptionInMenu -> SomeOptions...
          -> Extensions            -> AnotherExtensionOptionInMenu -> SomeOptions...
                                   -> SomeExtensionInMenu          -> SomeOptions...

This could be supported in the UI via a list of extensions that can be toggled individually to indicate whether to hide the menu options or not. It may be worth having two toggles, one for each menu (game/main).
