Define Soong phony rules in Make

To support dist-for-goals in Soong, we need to define all phony rules
in Make so that dist-for-goals can insert additional dependencies on
them.  Collect all the phony rules in phonySingleton and write them
out as Make rules when Soong is embedded in Make, or as blueprint.Phony
rules when Soong is run standalone.

Test: m checkbuild
