Retire redundant debug symbol resolution methods.

-fdebug-compilation-map and -fdebug-prefix-map are not supported by
Swift, and have required the assistance of DBGVersion 2 path

To simplify our debug symbol resolution story, we consolidate on
DBGVersion 2, as recommended by engineers closer to LLDB.
