8352738: Implement JEP 520: JFR Method Timing and Tracing

[egahlin]

Could I have a review of this enhancement that will add tracing capabilities to JFR? There are opportunities for performance improvements in the implementation, but I would rather add them later and separately.

Testing: tier 1-3, test/jdk/jdk/jfr

Thanks
Erik

Are the suboptions/parameters specified to -XX:StartFlightRecording a supported interface that is tracked by the CSR? I'm just wondering about the method-timing review specified to report-on-exit for example.
