Changed SDL fullscreen calls order by Nebulaxin · Pull Request #8034 · MonoGame/MonoGame

Small fix based on #8030

Because of the order of SDL calls, when going fullscreen and
`GraphicsDeviceManager.HardwareModeSwitch` is true, fullscreen mode is
enabled before resizing

And because of that resolution is set to window size, not
`PreferredBackBufferWidth/Height`, and only then resolution is set to
`PreferredBackBufferWidth/Height`

In this fix window will switch to fullscreen mode only after resize
