Separate HAGS from "Game Mode" slider.

[Squtzy]

Is your feature request related to a problem? Please describe.
I'd like to see the HAGS setting be excluded from the Game Mode Slider. As this is something I disable on my system due to some issues. When enabling the Game Mode slider I have to restart my PC a second time just to disable the HAGS setting.

Describe the solution you'd like
A separate slider to enable/disable the HAGS setting.

Describe alternatives you've considered
Have had to disable HAGS after running the tweaks and then restart my PC yet another time to disable it.
