NeoUI - Console toggle key rebind, intended for non-` key layouts

[nullsystem]

Description

• To workaround console not working for non-BACKQUOTE key layouts, allow the rebinding of the console to any key the user wants. This is also beneficial for people who also just want to put console to a separate key.
• Non-BACKQUOTE keys however requires the root menu to handle the key and toggleconsole itself, whereas BACKQUOTE key will always envoke. The root menu will handle it if it's active without a console opened. Otherwise the engine will envoke it even for non-BACKQUOTE itself if you're in-game without the root menu opened or the console is already opened.
• Nevra, who uses FR AZERTY confirmed this works well for him

Toolchain

• Windows MSVC VS2022
• Linux GCC Distro Native Arch/GCC 14

Can't toggle the console off with a rebound key under any situation, in menu, in game or in game with the menu open.

Neither is this possible when using "bind x toggleconsole" originally however so I'm guessing this is something that can't be fixed?

@AdamTadeusz I think it depends on what key you rebind. For example F5 worked well but "\" just relays to the console. In this case not much that can be done since the console out of our control, but it's good enough to workaround "`" issue.
