Revamp examples

Separate gallery example was created for widget and qml examples and
most example code was moved under those two gallery examples.

Examples left outside galleries for various reasons:
- audio: Requires multimedia, which is an optional addon
- openglseries: Requires OpenGL backend
- qmloscilloscope: Complicated hybrid C++/QML example
- qmlweather: Uses optional command line parameter
- zoomlinechart: Uses gestures, which require grabbing main window

Cleaned up the code of the remaining examples to same standard as
galleries.

Examples documentation will be updated in a separate commit.
