qmlprofiler: Add non-interactive mode and make it the default.

If you just run a test application through the profiler without any
further parameters, you want it to record the data the application
generates and then terminate itself.

[ChangeLog][QtQml][Behavior Change] Make qmlprofiler command line
interface better suited for scripting.
