ash: Eliminate PointerWatcherDelegate

ash: Eliminate PointerWatcherDelegate

Now that ash_sysui is unused the aura implementation is the only one and
we don't need a delegate.

* Remove CreatePointerWatcherDelegate() from ShellDelegate
* Rename PointerWatcherDelegateAura to PointerWatcherAdapter
* Call directly into PointerWatcherAdapter from WmShellAura and eliminate
ash::Shell::AddPointerWatcher
* Delete ash/sysui/pointer_watcher_delegate_mus.*

No behavior changes.
