Aura: Fix gray line at top of toolbar with translucent frames

Aura: Fix gray line at top of toolbar with translucent frames

The toolbar background painting code was copying pixels out of the toolbar background image with the wrong vertical offset.  I also moved the paint code into BrowserNonClientFrameViewAura so it can get the proper tabstrip vertical offset, and also because that's a more appropriate place for the logic.

BUG=113075
TEST=visual, ensure no "step" in the gradient at the bottom of the active tab or the top of the toolbar, for both maximized and restored windows
