Colin Blundell a406959e50 Add transient attachments and initial Metal support
This CL does the following:

* Adds a "transient attachment" bit to texture usage. This bit
  specifies that the created texture will be used only during
  this render pass.
* Adds a TransientAttachments Feature that gates the usage of
  transient attachments.
* Adds support for transient attachments on Metal, where they're
  used to create textures as memoryless.
* Adds validation tests and an E2T test of the feature.

A followup CL will add support in Vulkan.

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, 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.
