Reset in-memory JIT cache on game quit + fix Purge PPTC

Browse source 
Jit cache now fully resets when booting a game multiple times.
This should fix random jit cache crashes.
Also removed some redundant code related to region allocation and fixed
PPTC Purge not fully purging all PPTC files in the backup folder.
