cros: Fix O2TS observer list check empty failure.

ProfileDownloader could be destructed before refresh token is
available and leaving a dangling observer on PO2TS. Ensure it
is removed from PO2TS observer list on destruction.

Also checks if account_id matches the account on the profile and ignore unmatched calls.

Possible fix for crbug.com/294324.

(1) Make SearchTabHelper as a InstantServiceObserver.
(2) SearchTabHelper listens for most visited change events and theme background change events and tells the renderer via SearchIPCRouter.
(3) InstantPage no longer listens for instant service observer notifications.
(4) InstantPage no longer sends MostVisitedItems IPC Msg and ThemeBackgroundInfo IPC Msg to the renderer.
(4) Wrote new SearchIPCRouter and SearchIPCRouterPolicy unit tests.
(5) NOTIFICATION_INSTANT_SENT_MOST_VISITED_ITEMS notification is no longer used. Removed it from chrome_notification_types.cc.

Add xdisplaycheck as a dependency to net_unittests.

It is needed so net_unittests_run can archive xdisplaycheck.
