Remove Cocoa dependency from WebTextfieldTouchBar by moving
it from TabContentsController to BrowserWindowTouchBarController.

Hook up BrowserWindowTouchBarController to
AutofillPopupControllerImplMac on MacViews so that the
credit card touch bar can be updated.

Move the the logic that listens to WebContent changes to the
BrowserWindowTouchBarController. When the WebContents has
changed, BrowserWindowTouchBarController will update the
WebContents in BrowserWindowDefaultTouchBar and
WebTextfieldTouchBarController.

Modified SuggestedTextTouchBarController so that when its
WebContents has changed, it'll observe the new WebContents.
