Recreating it works fine on Intel GPU, no issues on validation but didnt work on other cards, there is a better way to do this from native without dangling around
Fixes https://github.com/Facepunch/sbox-issues/issues/9675
* Make MSAA setting work on editor SceneRenderingWidgets
MSAA settings never worked with editor viewport, only on game tab, now with playmode it always takes highest MSAA value from hardware regardless of what
Two things from this PR:
* Pass current engine MSAA setting when creating SceneRenderingWidget swapchain
* Add callback when video settings are changed, recreate swapchain when so
Replicates fine for all SceneRenderingWidgets, applies instantly
