Revert "Remove SwapChain from the API"

This reverts commit 966c91706b9a39c30bd3fc24f9f776a02cda8aaf.

Reason for revert: Make the Dawn LPM Fuzzer fail compilation.

Original change's description:
> Remove SwapChain from the API
>
> This applies the switch from manipulating a SwapChain object to calling
> Surface::configure that was brung to the standard webgpu.h a couple of
> months ago.
>
> I believe this needs a bit of extra work, but at this stage I need a
> review from people more familiar with the codebase to tell me if I am
> going in the right direction.
>
> The SwapChain object is still here, but no longer present in the API.
> Instances of the swap chain are now owned by the surface object. The
> test for surface capabilities is partly calling a method of the
> PhysicalDevice in order to have backend-specific capabilities.
>
> So far I mostly tested with the Vulkan backend, though I tried to
> provide a valid implementation for all backends.
>
> Reland changes:
> This fixes commit 167600, which was causing lock issues because the
> surface was failing at locking the device before calling it's internal
> SwapChain's methods like Present and GetTexture.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the 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.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A “native” implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
