[ios] Adds LocationBarCoordinator.

This CL adds the basics of an omnibox to the clean skeleton app.  The toolbar
now contains a real OmniboxTextFieldIOS with its associated machinery
(OmniboxViewIOS and LocationBarController).  The URL in the omnibox is kept up
to date during navigation and across tab switches.  Typing in the omnibox and
pressing Go will also navigate to the default match.

The omnibox popup is not yet implemented, and neither are the animations when
the omnibox gains or loses focus.

commit 7774ffbffc14fa93b82ef261a98d923b69db3209

[iOS] Prepare for the support of InputAssistantItems on iPad.

This CL cleans the Keyboard Accessory View (KAV) situation for the
web toolbar to support InputAssistantItems on iPad (1).
In particular, this CL:
- Removes keyboard_accessory_view.*.
  Now only new_keyboard_accessory_view.* is used.
- Removes HardwareKeyboardWatcher because it only works when there is
  a KAV (crbug.com/740898).
- Removes |-locationBarChanged| because it would only be used to
  record MobileFirstTextInOmnibox ( crbug.com/740611 ).
- Removes the |_keyboardAccessoryView| ivar. It was used when the KAV
  was not laid out with auto layout and had multiple modes.

We're not doing the new architecture anymore.
