Fog in Video Settings

Hello! In light of the fact that Mojang is making a lot of their debugging tools available to the public and removing code obfuscation, I would like to suggest a change.

In Java Edition, there is a debug hotkey hidden within the code that can be used to toggle fog (F3 + F). This hotkey can be enabled by setting the "MC_DEBUG_HOTKEY" debug property to "true".

The ability to toggle fog has a lot more potential than just being a debug tool. It could be converted into an option within the Video Settings menu. Being able to disable fog entirely could help improve performance on some devices, which can be especially helpful to users with lower-end hardware.
