Replaces #13041 . Did it somewhat differently, now works flawlessly on Linux for some reason, even when not recreating the surface on resize. Doesn't yet use oldSwapchain though, which will be required for switching vsync mode without stalling the GPU in the future.
Also enables the VSync setting on more platforms. There's more work to be done there though.
Shortens some logging, too.
The end goal of this stuff is better control over the swapchain, including seamless switches between vsync and not, for better unthrottle when vsynced, this is just a step on the way there though.
Also (accidentally, but decided to go with it) includes the fix for the issue @Anuskuss found with Vulkan and vsync and unthrottling.
