Reland "[WGPUFuture] Update buffer mapping in wire to keep reference to Buffer."

This is a reland of commit b445b0be7f620f1a662b7d835adbf59675fb45ea

Original change's description:
> [WGPUFuture] Update buffer mapping in wire to keep reference to Buffer.
>
> - Also updates buffer mapping on the wire to be more consistent with
>   other async future functions.
> - Note that buffer release no longer causes map async callbacks to
>   trigger since the event holds a reference to the buffer now.
>
> Bug: dawn:2061

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.
