RFR: 8326838: JFR: Native mirror events

[Erik Gahlin]

Hi,

Could I have a review of a change that provides infrastructure for emitting JDK events with metadata defined in native, such structs, enum constants.and references to native artefacts. If an event in the JDK has the same name as an event defined in metadata.xml, the metadata for the native event is used.

I also fixed an incorrect exception message in the TypeLibrary class.

Testing: jdk/jdk/jfr  and manual validatation that native metadata is picked by a JDK event.

Thanks
Erik
