[Toolkit.Graphics] Monitor index is ignored when going to fullscreen.

[ArtiomCiumac]

When switching to fullscreen - the monitor index is ignored and the application is always set to the primary monitor, this can be reproduced in MonitorInfo Toolkit sample.

i believe this is related to issue #326

if i revert the fullscreen-switching code in SwapChainGraphicsPresenter to

swapChain.ResizeTarget(ref description);
swapChain.SetFullscreenState(true, output);

then the MonitorInfo sample correctly switches to the given output.

the new fullscreen-switching is done in the function CreateSwapChainForDesktop() where i dont see the PrefferedOutputIndex being mentioned at all.
