refactor(DataTable): convert from class to functional component

[adamalston]

Partially addresses https://github.com/carbon-design-system/carbon/issues/19177

Converted DataTable from a class to a functional component.

Changelog

Changed

• Converted DataTable from a class to a functional component.

Testing / Reviewing

I left some TODOs with questions.

I planned to address the TODOs that are not tagged to the Carbon reviewers in a follow-up pull request, unless someone thinks they should be addressed now. My goal with these changes, given the nature of this component, was to leave as much unchanged as possible. I've added a third part to https://github.com/carbon-design-system/carbon/issues/19177.
