QmlProfiler: Make creation of local RunControls more flexible

In order for plugins to create a RunControl for locally running
applications that do not use LocalApplicationRunConfiguration it is
required to export an API that takes care of the internal setup. Also this
removes the hard dependency on LocalApplicationRunConfiguration.

We don't want to expose Internal classes in public API, so we have to
make QmlProfiler::Internal::QmlProfilerRunControl and
QmlProfiler::Internal::QmlProfilerStateManager public.

Also, AbstractQmlProfilerRunner doesn't do anything useful and can be
removed.
