Add new accuracy control for PUTLLUC accuracy setting (non-TSX)

Browse source 
With the option enabled GET commands are blocked until the current PUTLLC/PUTLLUC executer on that address finishes

Additional improvements:
- Minor race fix of sys_ppu_thread_exit (wait until the writer finishes)
- Max number of ppu threads bumped to 8
