Feature: Static membership for aiokafka broker (group_instance_id)

Hi!

Seems like aiokafka broker missing group_instance_id argument which required for static membership to work.

https://aiokafka.readthedocs.io/en/stable/api.html
```python
group_instance_id (str or None) – name of the group instance ID used for static membership (KIP-345)
```

For confluent kafka it exists https://github.com/ag2ai/faststream/pull/2606
