This is a copy of D51369722 to make it so that it preserves the file history
CalculateLayout.cpp is massive and approaching 3k lines. I added a few large functions dealing with layout of absolute nodes and was thinking it would be nice if that logic was just in its own file so it was more isolated and easier to reason about. So I made AbsoluteLayout.cpp and AbsoluteLayout.h to house this logic. In order for this to work I had to expose calculateLayoutInternal in CalculateLayout.h as layoutAbsoluteChild calls it. This is unideal and I would like to find a better way...
I also make LayoutUtils.h to house misc small helper methods as they are called in AbsoluteLayout.cpp and CalculateLayout.cpp
