refactor: remove RabbitQueue & RabbitExchange hashes

[Lancetnik]

These classes are using to cache real connection objects https://github.com/airtai/faststream/blob/0.6.0/faststream/rabbit/helpers/declarer.py#L15-L16

So, we should use hash to be sure, that user call declarer for the same object
https://github.com/airtai/faststream/blob/0.6.0/faststream/rabbit/schemas/queue.py#L57

Thus, we should make a bunch of unit-tests to be prevent incorrect collisions

Well, the concept changed - I think, we should use just a names to cache queue & exchanges objects in declarer: https://github.com/airtai/faststream/blob/0.6.0/faststream/rabbit/helpers/declarer.py#L39

To validate queue misconfiguration we should compare returning RMQ object with the passed by user one here - https://github.com/airtai/faststream/blob/0.6.0/faststream/rabbit/helpers/declarer.py#L54 and raise an error if passed queue options differ from the a object

Also, we should make the same for exchanges as well

After these changes we will be able to remove RabbitQueue.__hash__ and RabbitExchange.__hash__ methods at all

The PR should be open to 0.6.0 branch
