Extract the code responsible for navigating within the custom tab activity (handling back button, close button, open in browser menu item). This class perhaps should also have a navigate() method for navigation to a new url, which will internally use CustomTabActivityTabController (https://crbug.com/1382496).

See CustomTabNavigationController.java here for a rough idea how this class may look like: https://chromium-review.googlesource.com/c/chromium/src/+/1382496

Replace usage of CustomTabActivity in DynamicModuleCoordinator with usage of CustomTabNavigationController.

Ensure the new class is unit-testable, write a few tests. 

This is a part of CustomTabActivity refactoring plan described in
