[Tree view] Dev of the new component absorbed from Carbon

Background

Carbon’s tree view component currently exist in Carbon react experimental: Tree view and is a very accessibility friendly navigational component. We have many use cases that could benefit from this component include IBM Docs and SDMA. We would like to build this component in Carbon for IBM.com web components, and later contribute any enhancement to Carbon react.

Design does not have time to schedule the work to design the enhancements to the Carbon version. We will absorb the component and make enhancements based on user feedback later.
