Remove tracing from JFR scrubbing operation

Tracing instrumentation in ScrubRecordingDataListener causes
build-time initialization of tracer classes during GraalVM
native-image compilation when the agent is attached via
-J-javaagent. This results in "Classes that should be initialized
at run time got initialized during image building" errors.

Removing the spans/metrics maintains native-image compatibility
while preserving the core scrubbing functionality.
