Add option to disable Real Time Clock

[obnoxiousmods]

Some times users may want to disable RTC so that games act differently, games like pokemon e/s/r with their RNG and etc.

isnt that what this option is for?

I dont know.

Disabling that option seemingly does absolutely nothing unfortunately

Force RTC only applies to cases where the emulator doesn't know the RTC to be present. If the emulator knows that the game has RTC as per the builtin game database, then the option indeed does nothing and there currently is no way to disable the RTC.
