When InstanceBase::ProcessEvents() iterates through list of devices, one device might be being destructed on another thread. Even if we try to increase ref count of that device inside the ProcessEvents(), the device might be in the middle of destructor call on another thread, increasing the ref count is invalid in this case. This CL attempts to fix this issue by removing the device's pointer from InstanceBase earlier: when DeviceBase::WillDropLastExternalRef() is called. After this point, any callback registered to this device will be forwarded to InstanceBase's callback queue instead.

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.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- 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.
