Aura: Update window frames, allow resize from outside window

Aura: Update window frames, allow resize from outside window

* New window frames, still behind a flag as there's more refinement to do for incognito, popups, and maximized windows.
* Translucent frames now only require a single layer the size of the window instead of two.  We may be able to cut the layer size in the future to the area of the window header + toolbar
* Rewrite BrowserNonClientFrameViewAura
* Use updated art assets from crrev.com/124602
* Allow windows optionally to specify that hit tests should include a region a few pixels outside the window. For Aura browser windows this area acts as non-client area resize handles which we need because the window frame borders are now very thin or not present at all.

BUG=113075
TEST=manual, visual inspection of browser active, inactive, incognito, popup, hosted, and app windows.  Updated aura_unittest for Window to check the expanded bounds.

File ui/views/widget/root_view.cc (right):

ui/views/widget/root_view.cc:312: widget_->SetCursor(gfx::kNullCursor);
I tested this on Windows and this entire "else if" block does not appear to
execute at all.  Cursors worked correctly on Windows at the window edge.
