Unification of desktop run configurations, step 1

First step, move {DesktopQt,Qbs,CMake}RunConfiguration{,Factory}
into the same new files.

This only moves down to QtSupport, not ProjectExplorer, as there
are in all three cases direct dependencies on QtSupport. Long term
I would expect them to move further down.
