This change updates our runtime metadata registrations to retain whether they were included due to
-H:Preserve. This information is needed for differential tracing.To track the "preserved" state, this change:
boolean preservedfield toRuntimeConditionSet, which is renamed toRuntimeDynamicAccessMetadata(no size change)JNIAccessible[Field,Method](no size change).boolean preservedfield toJNIAccessibleClass(24 -> 32 bytes, per JOL). PR-bench did not report any image/footprint regressions.Preserved resources are more involved to track, so they are deferred for this change (GR-68918).
