Check bind group layout with storage texture in pipeline descriptors

This patch adds all the validations on the use of bind group layout with
read-only storage texture and write-only storage texture in the creation
of pipeline objects.

1. GPUBindGroupLayout.bindingType must match the type of the storage
   texture variable (read-only or write-only) in shader.
2. GPUBindGroupLayout.storageTextureFormat must be a valid texture
   format that supports STORAGE usage.
3. GPUBindGroupLayout.storageTextureFormat must match the storage
   texture format declaration in shader.
4. GPUBindGroupLayout.textureDimension must match the storage texture
   dimension declared in shader.

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.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • 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
