Use system game language for PSP UI not PPSSPP UI language

What should happen

I want english for the PPSSPP UI stuff but in game another language. But I see that PSP system UI like save dialog is in the same language like PPSSPP UI, instead of the game language you set in PPSSPP system settings. It would be more consistent if that also used the game or PSP language.

Who would this benefit

everyone who want to play in their language and want full psp feeling with consistent behavior. But keeping the PPSSPP settings UI in english for better understanding, because translations are not always helpful here, and you get better help in english from e.g. forums and github.

Platform (if relevant)

macOS

Games this would be useful in

all games who uses psp ui e.g. save manager
