Python: FunctionResultContent hash fix to handle lists/sets

[moonbox3]

Motivation and Context

Currently, the hash function in FunctionResultContent does not properly handle types of list or set. Adding the proper handling to turn these into a tuple, and then the hash function works properly.

Description

This PR:

• Makes sure the FunctionResultContent __hash__ method can properly handle mutable types like lists or sets
• Adds tests to ensure the new behavior works as expected
• Ensures the create message content method can handle lists or sets when generating the content and the model can only accept a string.
• Fixes Python: unhashable type 'list' exception in function_result_content __hash__ function #9977

Contribution Checklist

• The code builds clean without any errors or warnings
• The PR follows the SK Contribution Guidelines and the pre-submission formatting script raises no violations
• All unit tests pass, and I have added new tests where possible
• I didn't break anyone 😄
