Spike about adapting Jenny to our code

After the work of QTBUG-104067, it was decided to use Jenny  for automatically generate C++ code from Android API's.

In this story we want to investigate if using Jenny without any change in the lib is possible for our needs, or if we should fork/replace it with our own library.

Open questions to answer:

• remove/hide jenny namespace
• use Qt memory management and functions
• configurability
