D3D11: Create shader objects asynchronously.

This change makes the creation of D3D11 shader objects
(ID3D11VertexShader, etc.) asynchronous. Currently, these objects must
be ready when a pipeline is used for command buffer encoding. However,
they are only strictly needed when the command buffer is submitted.

By deferring the creation until submission, this change avoids blocking
the encoding thread if the shader takes a long time to be created. This
allows for more ample time for shader creation to happen in parallel
with command recording.

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.
