Add support for compiling QML/JS files ahead of time in resources

This is bringing over the loading infrastructure from the Qt Quick
Compiler that allows embedding qml/js files in resources and compiling
them ahead of time.

At the moment, the approach of generating one cpp file per qml/js file
and the loader stub is needed because the build system does not support
dynamic resource generation. In addition, as per QTBUG-60961, we must
ensure that the generated data structures are aligned.

To retain compatibility this is enabled via CONFIG += qtquickcompiler,
but we may need to find a new name (but should keep the old one in any
case).
