CEF3: OSR Accessibility

[GoogleCodeExporter]

This patch implements Accessibility support for Offscreen Rendering Mode. On 
Windows it will expose IAccessible object instance of OSR browsers which allow 
to use different accessibility tools like UI test automation or screen readers 
with non native windows controls.

Patch also fix incorrect CefRenderWidgetHostViewOSR::GetViewBounds() return 
value. GetViewBounds() must return bounds in screen coordinates (as non OSR 
mode does).
