📢 Type of change

• Bugfix
• New feature
• Enhancement
• Refactoring

📜 Description

Added a new SqsContainerOptions option : messageGrouping. True by default. When false, a new MessageSinkAdapter is used. This adapter does not have grouping function.

I was wondering whether I should add the new option messageGrouping in the @SqsListener annotation or leave the configuration only in the factory.
Although the option is only relevant for FIFO Queues with a listener in batch mode, I've decided to put the option in @SqsListener, which will make it easier for library users to configure.

I don't know if the name messageGrouping is meaningful enough, I can change it if necessary.

💡 Motivation and Context

Fix the issue #1041

💚 How did you test it?

I added a test in SqsFifoIntegrationTests. In this test, I configure a new listener with messageGrouping set to false. I send several messages from two different message groups.
In the listener, I verify that the batch of messages received contains messages from different message groups. Then, I check that all messages from each group have been received.
