TokenizingTextBox SelectionMode is ignored

[michael-hawker]

Filed from CommunityToolkit/Graph-Controls#65

Describe the bug

SelectionMode (from ListViewBase) in the TokenizingTextBox doesn't do anything for the control.

Expected behavior

I'm wondering if we can hide this, or at least document that it's ignored? We need some design thought here?

I have a draft PR up to handle the support requested in the original issue, which is to limit the number of potential tokens in the underlying TokenizingTextBox. However, I did not address the actual implementation of the ListViewBase.SelectionMode property.

So even once that PR is merged, I think this issue should remain open until we document the lack of support for the ListViewBase.SelectionMode property, or take the effort to add support in regards to actual token "selection" (meaning, how may existing tokens can be highlighted/selected for clipboard interactions).
