Ben Clayton 0e3d4fcbd4 dawn_node: Prevent setImmediate() being queued multiple times
The AsyncRunner will enqueue a call to `Device::Tick()` when the runner count moves from 0 async tasks to 1.

It has been observed that some 'async' tasks are actually synchronious, which results in multiple tick callbacks being enqueued before the first has a chance to run.
Fix this by using another boolean to track whether the function has been queued.

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 on Windows 10
    • Metal on macOS and iOS
    • Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
    • OpenGL as best effort where available
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
