Dawn.node: make onuncapturederror work.

Note, the way it's supposed to work is, setting
onuncapturederror adds a listener via addEventListener
that calls the callback.

Setting onuncapturederror to a new callback changes the
callback in the existing listener.

Setting ouncapturederror to null removes the listener
via removeEventListener.

This effects the order these are called. Tests were added in
webgpu:api,operation,uncapturederror:onuncapturederror_order_wrt_addEventListener:*

I could have hardcoded that behavior for onuncapturederror specifically
but looking at Blink, event_target.cc, it's implemented something like
this as it's more generic for more attributes. It seems unlikely there
will be more onxxx attributes in the future but the code isn't all that
much larger than hard coding for one attribute.

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.
