Bug 1979114 - Add a new JS sources feature to the profiler r=mstange,profiler-reviewers

I add this feature now, so I can use it in the following patch when we
are retrieving the JS sources from the JS engine.

This feature is currently not on by default until we iron out all the
issues and defails.
