[Feature]: v9 Tree make active state declarative

[bsunderhus]

Library

React Components / v9 (@fluentui/react-components)

Describe the feature that you would like added

Current behaviour

Currently the active state is only visible while clicking over a tree item:

The active state presents the tree item with a different background color and also keeps actions slot as visible.

New behaviour

Add a property or some sort of internal state that allows the user to force declare that a given item is on the active state, this will allow customisation from the user side on cases that this state might be relevant.
