layers: Create APIDump[NoAddr]Cpp layers using c++ string and streams

This is fully functional version of APIDump & APIDumpNoAddr using std::string and i/o streams
Hopefully this will fix a few random crashes that were being hit with rendersystemtests & APIDump
Long term we won't keep generating so many different APIDump layers.
The main APIDump layer will be the Cpp version and it will have settings file options to vary file i/o and noaddr along with any new options.
We should keep the C version of APIDump around until we're sure we don't need it, though.
