Description
Currently, interval processor will always send a metrics instance downstream, at every interval tick. Even if the instance is empty. This PR fixes this, to reduce spam, and so downstream exporters don't need to do extra filtering
Link to tracking issue
Fixes #37905
Testing
Locally built and ran the processor to see that no empty metrics are exported
