Currently Buffer doesn't distinguish Map request callback fired by device. For example if buffer.MapAsync(), buffer.Unmap(), and buffer.MapAsync() are called in this order before the first MapAsync() finishes the MapAsync callback provided by application for the first MapAsync() is fired when Map request callback for the first MapAsync() is fired by device although the first MapAsync callback provided by application shouldn't be fired because it is already unmapped. This commit resolves this problem by assigning MapRequestId to Map request and distinguishing the callback fired by device.

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.
