Time revamp (#2304)

* Don't Use OSCalendarTime for Speedrun Timing

- Shouldn't rely on OSTicksToCalendarTime since it will be changed to handle time zone conversion, and that doesn't make sense on elapsed time

* Use OSGetSystemTime Extension

- Fixes desyncing issues with save file time and a couple other odd instances, particularly on mobile platforms that suspend apps

* Time revamp

* Update aurora

* Split IGT/RTA calculations

* Shift-Turbo to slow down
