Title: Allow scaling for METRO/DX/XAML

https://github.com/mono/MonoGame/issues/1487

When setting the backbuffer/swapChain to other than the native
resolution
SwapChainBackgroundPanel doesn't get notified.
One way to force it to update and change the resolution (scaling) is to
set again the SwapChain.
