Create a heavy QML application for benchmarking real-world full stack performance

The benchmark application should consist of the following measurements:

1. Start-up time from application creation to first frame.
2. time between frames after startup.
3. memory consumption

The benchmark should include the following features:

1. Complex fonts. Provide a switch for enabling DFG fonts.
2. Shaders with shader cache
3. Images and texture compression

The application should be heavy enough to simulate a plausible customer use-case.
