dawn/node: Avoid exception on teardown

If node is shutdown without first explicitly destroying the GPUDevice, the device's destructor will be called, which would automatically destroy the dawn device.

Before doing this, it would first reject the lost-device promise. With newer versions of node, attempting to construct new GC'd objects on NodeJS tear-down triggers a fatal error.

Work around this by adding a new state to promises, that allows promises to be destroyed without first being rejected or resolved, and without raising a 'Promise not resolved or rejected' fatal message.

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.
