Change Summary
Split out from the original combined PR #2717.
Adds a contrib processor that promotes decoded Microsoft Common Schema log attributes into typed OTLP log fields.
This processor is independent of the user_events receiver. It expects Common Schema fields to already be decoded into log attributes, for example from EventHeader payloads.
Also adds unit tests for supported promotion behavior and pass-through cases.
