Improve the structure of the output generated by qmltc

Make an effort to separate user-visible APIs from internal code relevant
to qmltc

In the process of doing it, make tst_qmltc_examples::helloWorld() test
less brittle by using QMap instead of QHash when dumping C++ member
functions of the type. QHash does not guarantee that the keys are
ordered while QMap does (via operator "<")

Pick-to: 6.3
