SwapChainVk: handle mismatching size and usage with a blit
In Vulkan the swapchain can stop working if the window resizes and
doesn't match the size of the swapchain images anymore. WebGPU
applications might not handle resizes instantly, so if the swapchain
becomes incompatible we give them a temporary texture that we'll then
blit inside the real swapchain texture.
This also handles the case where the application requires more usages
than what the swapchain can support.
In addition, temporary checks are added that fail swapchain creation if
the VkSurface doesn't support BGRA8Unorm which is the only allowed
format for WebGPU swapchains at the moment.
SwapChainTests should now work on Vulkan and are enabled.
