RFR: 8365550: JFR: The active-settings view should not use LAST_BATCH

[Erik Gahlin]

Could I have a review of the change that updates the active-settings query to use LAST instead of LAST_BATCH?

The problem with using LAST_BATCH is that it doesn’t work with older recordings where the jdk.ActiveSetting event was not emitted as a batch, or with later recordings where a single setting is changed programmatically.

Testing: jdk/jdk/jfr

Thanks
Erik
