[fence_manager, ui] antiflicker fix + toggle integration (#4004)

Browse source 
tldr: we (me and maran) found the missing piece to make delay_fence and should_flush coop and cover all remaining flicker issues tested so far.
the lil change is in src/video_core/fence_manager.h
the rest is toggle stuff.

END

(credits rolls up)

post credits scene for the toggle drama:

i've been forced to use custom builds for around 1 year now, coz gpu mode above fast was pulling performance down yet not covering flicker entirely in most games tested. and we know that it's a mess to rely on gpu mode as it brings along a bunch of undesired stuff.
i need this toggle. and i've seem far less relevant before, so hey, gimme this one so i can call it mine :3
