Pass output through the RunControl instead of the DebuggerManager.

Plan is to identify make identify an IDebuggerEngine incarnation with
a RunControl.

Case 1 from tst_HighlighterEngine::testDynamicContexts covers this case.

This reverts commit 47885c11.

changes to them *really* should cause a rebuild ...

This replaces most uses of DebuggerStartParameters by DebuggerRunControl
which is a simple RunControl with a DebuggerStartParameters member.

Plan is to move all global state to the run controls, and possibly
introduce specialized ones for core debugging etc.

Also removed TokenUnderCursor as it's functionality is in the token cache.
