[Feature]: Build Option To Enable/Disable TPG State Monitoring

[aeoranday]

Description

The functionality of TPG's internal state monitor should become a build option instead of a configuration enable/disable.

Potential impact radius

Small/Isolated

Reason for change

It was noticed during performance testing that the logic for the internal state monitoring was a non-negligible cost to CPU usage while the monitoring was disabled. Shifting the functionality into a build option better preserves the performance requirement for TPG.

Suggested implementations

Both tpglibs and fdreadoutlibs should receive this build option change, where:

• tpglibs toggles whether the functionality of internal state monitoring is present or not,
• fdreadoutlibs continues to collect and publish the results when enabled and configured and emits a warning when disabled and configured.

Testing suggestions

Testing may be done in local test sessions to confirm the warning is present and that the monitored states are not being written. A test for performance impact must be done using a high TP rate and likely requires an EHN1 detector.
