[AOT] Fix issues when we want to log some telemetry in AOT version (#40148)

<!-- Enter a brief description/summary of your PR here. What does it
fix/what does it change/how was it tested (even manually, if necessary)?
-->
## Summary of the Pull Request
Telemetry.write will serialize all of the whole object graph. So we need
to ensure it will not be trimmed.

This is a safe PR because it doesn't apply any logic change. If you
disable the AOT feature, this PR won't take any effect.
