ThreadUtil shipped a scope lock and a mutex implementation, which can be removed since we now have these in the standard library. This lets us clean up this header which get included everywhere (through profiler includes). Tested By: Angen and Stan Differential Revision: https://code.wildfiregames.com/D1915 This was SVN commit r22344.
