Revert of Migrate BrowserAccessibility windows unique id handling to AXPlatformNodeWin. (patchset #4 id:80001 of https://codereview.chromium.org/2981083002/ )
Reason for revert:
Revert due to crbug 748472. Will reland w/ fix after merge to M61 branch.
Original issue's description:
> Migrate BrowserAccessibility windows unique id handling to AXPlatformNodeWin.
>
> Global identifiers are allocated out of ui::GetNextAXPlatformNodeUniqueId
> currently. Both BrowserAccessibility and the AXPlatform code both independently
> Assign a unique id during object creation.
>
> What we want to have happen is for the BrowserAccessibilityComWin class,
> and it�s typical owner, the BrowserAccessibilityWin, to share the same unique
> id. This makes it easier to reason about as well as necessary to be able to
> Implement get_uniqueID().
>
> This CL makes private the |unique_id_| used in both above base classes private
> and forces all access through virtual class methods. The BrowserAccessibilityWin
> overrides and implements in terms of AXPlatformNodeWin.
