Tell the QML debug server exactly what services we expect

Browse Source 
The services need to be loaded before the first QML engine is created.
The first QML engine may be created before a client connects. When the
JavaScript debug service is loaded the engine is put into interpreter
mode as we don't support debugging in JIT mode. Profiling, however
should be done in JIT mode, whenever possible.

Thus, in order to avoid the loading of unnecessary plugins and to get
better results from the QML profiler we tell the debug server which
services we expect, even before the client connects. Qt 5.6 will support
additional command line arguments to specify the services and this
change uses them.
