[Bug][client] Consumer implementation might change message processing order when ack timeout is set

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.

### Read release policy

- [X] I understand that unsupported versions don't get bug fixes. I will attempt to reproduce the issue on a supported version of Pulsar client and Pulsar broker.

### Version

master

### Minimal reproduce step

Analysed by looking at code in MultiTopicsConsumerImpl

https://github.com/apache/pulsar/blob/fb80007a47deaadb82d0b1b1e4fcd6ca04c05c9c/pulsar-client/src/main/java/org/apache/pulsar/client/impl/MultiTopicsConsumerImpl.java#L889-L911

and ConsumerImpl

### What did you expect to see?

Message ordering shouldn't change.

### What did you see instead?

A random message gets pulled out of the queue and it is requested for redelivery. Message ordering could change, let's say when Key_Shared is used, this is a problem. There are also other problems in this code since this logic races with message consuming by the application or message listener.

### Anything else?

_No response_
