[core] Add option to control Host MMU Emulation (#324)

Browse source 
This adds an option to enable or disable Host MMU Emulation [Android/PC], brings better config per-game handling with Disable Buffer Reorder, disables Flush Debug Lines by Log, option which was enabled by default on Android/PC taxing performance and translates to all supported languages the recent changes.

Leaves room for NCE improvements in the foreseable future.
