RFR: 8343026: JFR: Index into fields in the topFrame [v2]

[Erik Gahlin]

> Could I have a review of a change that allows 'jfr view' queries to reference nested fields for a top frame.
> 
> Testing: jdk/jdk/jfr and diff of 'jfr view all-views' before and after the change.
> 
> This change will not impact the output of the exiting views, but it helps OpenJDK developers diagnose issues, for example, print 'lineNumber', (frame) 'type' and 'bytecodeIndex' of the top frame.
> 
> Thanks
> Erik
