This patch makes the error codes in nsError.h be generated by a python script.
This gives us the opportunity to add rust code generation in parallel with the
C++ code generation, which will happen in part 2.
This patch also reworks the name calculation in ErrorNames.cpp to use generated
code by the python script.
