The primary goal here: move the custom overloads for `hphp_raw_ptr` of static/dynamic cast in `Base.h` out of the boost namespace, into HPHP namespace (which already uses normal boost versions). This means all casting, to be consistent, should happen in the HPHP namespace Differential Revision: D959867
