Revert "D3D11: Manage builtin variables with ImmediateConstantTracker"

This reverts commit 6547ea2af9ffd3502f3e7e4873089f20a9b1d270.

Reason for revert: Cause corruption in Graphite rendering on D3D11.
Possibly the built-in variables (firstVertex, firstInstance) were
not passed to shaders correctly.

Original change's description:
> D3D11: Manage builtin variables with ImmediateConstantTracker
>
> This CL replaces write to uniform buffer mechanism with
> ImmediateConstantTracker to manage builtin variables in D3D11 backend.
>
> It is the base to switch to use ImmediateConstants to support internal
> immediate constants.

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.
