RFR: 8271232: JFR: Scrub recording data [v3]

[Erik Gahlin]

> Hi,
> 
> Could I have review of an enhancement that allows .jfr files to be scrubbed for sensitive information, either by a call to `RecordingFile::write(Path, Predicate<RecordedEvent>) `or from command line with `jfr scrub`. For details, see CSR.
> 
> Testing: jdk/jdk/jfr + manual testing with a SPECjbb recording with all events enabled
> 
> Thanks
> Erik
