This cleans up many un-necessary header includes, either simply providing nothing or forward declarations in their place. No major compilation time change here, though this does reduce depencies in some headers. Also fix up old MacOS STL-include fixes that are no longer relevant. Differential Revision: https://code.wildfiregames.com/D3128 This was SVN commit r24227.
