D3D11: Always use custom device context state.

Currently we only use a custom device context state when we share the
D3D11 device. We swap in & activate it during render pass, compute pass'
executions. The purpose is to avoid Dawn messing up the D3D state of
other modules such as ANGLE, video decoder, etc.

However, this makes the behavior inconsistent between tests and chrome
use cases which share the D3D11 device.

This CL forces D3D11 backend to always use the custom device context
state. It will make the tests easier.

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.
