[dawn][native] Add operator== for wgpu::TextureComponentSwizzle

Add and use operator== and != for wgpu::TextureComponentSwizzle.

Also remove TODOs about optimizing view creation for swizzles on <4
channel textures because I realized there's probably no point in doing
that. (It's a minor optimization to prevent creating view objects, and
it only applies in situations where the app is creating views with
swizzles that are equivalent to no swizzle, which should be uncommon
since it's not useful for anything.)

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.
