core,common,yuzu qt: Add CPU accuracy option 'Auto'

Browse source 
The current CPU accuracy settings in yuzu are fairly polarized and
require more than common knowledge to know what the optimal settings for
yuzu would be. This adds a curated option called 'Auto' that applies a
few at the moment known-good unsafe optimizations to Dynarmic.
