chore(): Emit events in batch and index process event ids in batch (#12097)

**What**
First iteration to prevent events from overwhelming the systems.
- Group emitted event ids when possible instead of creating a message per id which leads to reduced amount of events to process massively in cases of import for example
- Update the index engine to process event data in batches of 100
- Update event handling by the index engine to be able to upsert by batch as well
- Fix index engine build config for intermediate listeners inferrence
