This solves an issues where when switching swapchains the previous one was destroyed before the new one was created, doing so detached itself from the Surface, which in turn made the new swapchain not do a graceful transition via vkSwapchainCreateInfoKHR::oldSwapchain. Keeping the reference on the surface makes sure we always have knowledge of the previous swapchain when replacing it. It requires re-working the lifetime model of NewSwapChainBase to not require a call to DetachFromSurface in the destructor, and having the Device explicitly tell a swapchain it got attached on creation (otherwise there are ASSERTs firing when swapchain creation fails). In addition, backends are changed to use a SwapChain::Create method and fail with a validation error (for now) when the previous swapchain didn't use the same API. vulkan::SwapChain is updated to use the previous swapchain's device's fenced deleter to destroy it which is important in the device switching tests. The SwapChainValidationTests are updated because with the lifetime changes the texture view can be kept alive after the application has lost the last reference to the wgpu::SwapChain. TBRing since it was reviewed in a different CL (but for the wrong branch).

Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard.
More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL.
Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
- WebGPU C/C++ headers that applications and other building blocks use.
- The
webgpu.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs:
- D3D12 on Windows 10
- Metal on macOS and iOS
- Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
- OpenGL as best effort where available
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
