Basic metro snap view omnibox.

Implementation of basic metro snap view omnibox. 

When snapped to a 20% view, the omnibox is now made visible, but disabled. When unsnapped, the original location bar is restored.

Also fixes an access violation in omnibox_view_win.

BUG=141546

Hi Scott,
  Please could you take a look at this change for adding an address bar to metro
snap mode?
Thanks!
Robert

Can this be made separated? So it's clear what fixes this access violation?
Probably Peter or Mike (msw) should look at this as well.

Thanks Thiago, sent Peter a CL for the omnibox fix, I'll leave the code here as
well until the other is committed since this exposes the crash quite readily.

Peter, Thiago suggested I should run the Omnibox stuff by you too. Would you
mind taking a peek?

You don't need both Peter and myself. I'm removing myself.

Yep, sounds like. Many thanks for taking a look. At least one small bug fix came
out of it :)
