Revert of Remove override of View::HitTestRect() from BookmarkBarView

Revert of Remove override of View::HitTestRect() from BookmarkBarView (https://chromiumcodereview.appspot.com/286313003/)

Reason for revert:
Items on the bookmark bar can still be highlighted and tooltips are shown when the omnibox popup is open. tdanderson@ will investigate.

Original issue's description:
> Remove override of View::HitTestRect() from BookmarkBarView
> 
> The override of View::HitTestRect() in BookmarkBarView checks
> for the state of the omnibox popup to determine whether or not the
> bookmark bar can accept events. Since this is unrelated to location,
> it is better to move this logic into an override of
> EventTarget::CanAcceptEvent() instead.
