RFR: 8365815: JFR: Update metadata.xml with 'jfr query' examples

Wed Aug 20 20:52:04 UTC 2025

Could I have a review of a PR that adds a couple of 'jfr query' examples to metadata.xml?

It turns out that the EventDuration event doesn't work because it has no fields. The fix is to remove the class-specific commit() method and constructor for events without fields.

Testing: test/jdk/jdk/jfr + tier1

Thanks
Erik
