Eliminates a static initializer in kUnusedFormat (in Texture.cpp) by making dawn::native::Format constexpr-constructible. kUnusedFormat doesn't actually have to be constexpr to fix this, but it adds explicit enforcement that it's constexpr-constructible. Includes some extra initializers as a workaround for a bug in the old version of MSVC (14.26) that's on Kokoro. amaiorano figured out how to reproduce it locally, with a local install of VS2019 and this magic CMake incantation: $ cmake -G "Visual Studio 16 2019" -T v142,version=14.26 ..

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
- Tint is a compiler for the WebGPU Shader Language (WGSL).
