[Macs] Adds a RenderWidgetHostView method to tell the view to take focus only on a mouse down event. This will allow us to click on instant results without dismissing the omnibox popup.

BUG=56385
TEST=No visible impact, yet.
TEST=Should still be able to tab from the omnibox into webpages.
TEST=Clicking on a webpage should transfer focus to the page.
