Partially externalize WebDriver tests

This change does a few things:

  1. Partially externalized WebDriver tests by using ChromeDriver
     as an implementation of WebDriver API in the external build.
  2. Refactored WebDriverRule.java to decouple the creation and
     using of WebDriver related stuff so we can have different
     implementations in internal and external builds.
  3. Refactored the usage of some internal libraries to have a
     central place to store all of them to make it easier to
     remove them in the external build.
