RFR: 8353226: JFR: emit old object samples must be transitive closure complete for segment

Sun Mar 30 12:13:55 UTC 2025

Greetings,

EventEmitter::write_events() only serializes blobified stack traces as part of old object checkpoint serialization. Still, it categorically writes a stack trace id as part of the event, even for non-blobified stack traces. As a result, the segment is incomplete. Stack traces must be serialized directly from the leak profiler repository to ensure closure. 

Testing: jdk_jfr

Thanks
Markus
