[iOS][coordinator] Modernize toolbar coordinators.

This CL removes public properties for WebStateList, BrowserState and
dispatcher values and updates the coordinators implementation to get
them from self.browser.
The refactored coordinators:
 - Adaptive Toolbar Coordinator
 - Primary Toolbar Coordinator
 - Secondary Toolbar Coordinator.
