Reland: Add a usage parameter to TextureView creation.

This allows views to use a subset of usages from the source texture's
usages and use formats that may not be compatible with all of the
source textures usages.

https://github.com/gpuweb/gpuweb/compare/2dc56f29788a...010f5c9ddfd2

Reland additions:
Only validate explicit view usage for now. Until it is possible to
request explicit usages from the WebGPU API, the RGBA8UnormSrgb and
BGRA8UnormSrgb would not be usable as view formats if the base
texture has StorageBinding usage. Remove the StorageBinding usage in
this case and emit a warning.

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.
