RFR: 8354949: JFR: Split up the EventInstrumentation class [v3]

[Erik Gahlin]

> Could I have a review of a PR that cleans up the EventInstrumentation class and moves the non-modifying parts into a separate class (ClassInspector)? 
> 
> I deleted the code that removes the instrumentation (buildUninstrumented), because it has never been used. If there should be a need for it in the future, it's not hard to add code that inserts empty method bodies.
> 
> Testing: tier1 + jdk/jdk/jfr/test
> 
> Thanks
> Erik
