Revert "D3D11: Change GetScopedPendingCommandContext() to return ResultOrError"

This reverts commit cf904626134ad498f6563bf2b5cf67b49e7f4eee.

Reason for revert: The previous commit caused Buffer::DestroyImpl to
delete buffers while they were still mapped. This state causes
stability issues or crashes on Intel drivers.

Original change's description:
> D3D11: Change GetScopedPendingCommandContext() to return ResultOrError
>
> This is to allow operations done inside GetScopedPendingCommandContext()
> to return error. For example we could change PerformDeferredUnmaps()
> to return MaybeError in future CL.

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.
