D3D12: Don't skip flushes when the recording context is not open.

Make the CommandRecordingContext always open instead by initializing it
on Queue creation and reinitializing it after a submit. This allowed
removing all the IsOpen() logic. In order to move in the queue the logic to
reinitialize the context, the CommandAllocatorManager was folded in the
Queue, where allocation of ID3D12CommandLists and their reuse can be
controlled more precisely.

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.
