[DocsUI M3] Convert ListView to RecyclerView for nav roots

Convert the navigation tree from ListView to RecyclerView in order
to fix the tab cycle problem:
* Create an interface to abstarct all list/adapter operations.
* Implement the interface for both ListView and RecyclerView.
* The RootsFragment can rely on the abstract interface and no need
  to care about the underlying implementations, avoid if/else
  everywhere.

There's no new functionalities added, we just rely on the existing
tests.

Check the attached bug for demo.
