Expose more information in the compare_scenarios function

[FlorianJacta]

Description
The goal is to have more information as parameters of the comparator functions so that the user can create the proper comparison. For example, the user doesn't know in the comparison function which scenarios he is comparing.

An idea could be to have the data nodes themselves as parameters and not their data.

This issue comes from this discussion:
Avaiga/taipy-doc#932 (comment)

Acceptance Criteria

• Ensure new code is unit tested, and check code coverage is at least 90%
• Propagate any change on the demos and run all of them to ensure there is no breaking change
• Ensure any change is well documented

One concern I have is that a data node may belong to multiple scenarios depending on its scope.
Passing only the data nodes can't help you get the corresponding scenario.

The parent_id would be what interests me here.
