This PR changes GenerateJfrFiles.java so that the generated `JfrNativeSettings` union does not include JFR structs.`JfrNativeSettings` is meant to hold the settings for JFR events, but previously also included JFR structs such as MetaspaceSizes, StackFrame, CopyFailed, G1EvacuationStatistics, ObjectSpace, VirtualSpace. These are not events, but instead are JFR `Type`s, and so do not have settings such as stacktraces or thresholds.
The inclusion of JFR structs in `JfrNativeSettings` was problematic because it could cause a displacement between event ID and`JfrNativeSettings` array index (each index is meant to correspond with a specific event ID). Testing: - jdk/jdk/jfr - tier1 ------------- Commit messages: - Don't include JFR structs in the list of JFR events in generated files.
