Merge two queue submissions in Queue::SubmitImpl()

Currently Queue::SubmitImpl() may cause two queue submissions, one is
because of Tick() call which will submit pending commands if there are.
The other one is after converting frontend commands to backend command
buffer. Queue::SubmitImpl() will submit converted commands. However
usually queue submissions are expensive, so merge those two queue
submissions into one by not calling Tick() before converting frontend
commands, so pending commands and recorded commands can be submitted
together. After that, we call Tick() to resolve callbacks and perform
bookkeeping operations (deallocating memory for passed operations,
etc).

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the work-in-progress 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.
