[Mac] Fix TextSuggestionsTouchBarController Browser Tests

TextSuggestionsTouchBarController's browser tests were failing because
WebContents::IsFocusedElementEditable() returned false even after a
web page was loaded with an autofocused textfield.

A WindowedNotificationObserver was added to observe a change in focus
in a page. When the textfield is autofocused, this observer is
notified. By waiting on this observer, the tests can guarantee that
WebContents::IsFocusedElementEditable() is true and that the tests that
rely on that condition will pass.

Disabled tests were undisabled.
