Summary:
While individual getters and setters are added to the list of methods of
a class, property_def will hold them as a pair.
This will help defining accessors like C#'s where they're grouped.
Also update some eolian-cxx tests that were commented out.
Depends: D7262
Test Plan: run eolian-cxx tests
