[Feature Request] tri-state config

[CuddleBear92]

Quick summary

Per-Game configs should not mirror whatever the global setting is currently and lock those but rather only save and override the touched settings for the game while keeping the rest in sync with the global settings.

Details

Having the global settings always being underneth the per-game configs makes sense for larger shifts in norms with the emulator for settings that makes sense to always use at all times.

Per-game configs should only account for settings the user manually set, maybe in another color with the option to reset it to the current global (removing the override)

Having per-game configs to only contain changes or specific settings for the title and not every setting in the emulator would also make it much easier to share for multiple users.

See Yuzu for wanted experience.

Not sure if I agree with this as it will cause problems for people who thought they e.g saved write color buffers being enabled but it was actually coming from their global config. Then when they change their global config it disables WCB for multiple games they had configs for.

Personally I think all we need is settings on the emulator tab apart from disable native interface should be global, and not saved in custom configs. And possibly moved to the gui config file. Changing these settings is a real pain when you have a hundred games with custom configs, and I see no real reason for them to be game specific.
