Debugger: Make DebuggerRunTool (more) responsible for output

Make DebuggerRunTool accessible to downstream users, but remove
the non-standard handleApplicationOutput from the run control
itself to move it closer to the base run control.

LogChannel and Utils::OutputFormat should merge at some time.
