RFR: CODETOOLS-7902867: JOL: Use defined data model to print the header in class layout [v2]

[Aleksey Shipilev]

> JOLSample_10_DataModels does not work properly after CODETOOLS-7902866. It only takes care of the "actual" VM layout, ignoring the defined data model. We need to make ClassLayout accept the data model.
