NIFI-16123 Add Connection Status reporting to Process Session

[exceptionfactory]

Summary

NIFI-16123 Updates the framework ComponentMetricReporter interface with new methods for recording ConnectionStatusEvents when the StandardProcessSession commits transactions.

The implementation of the ConnectionStatusEvent follows the interface definition and builder pattern of the ProcessSessionEvent currently implemented in ComponentMetricReporter.

The new methods on ComponentMetricReporter include an enabled status indicator, allowing the StandardProcessSession to avoid unnecessary operations when the ComponentMetricReporter implementation does not support recording Connection Status Events.

The Connection Status Event recording enables exporting queued FlowFile information without depending on the StatusHistoryRepository for persistence and subsequent reporting.
