Add size parameter check in buffer mapAsync in wire server

This patch add the size parameter check in buffer mapAsync in dawn
wire server to make sure that it is not WGPU_WHOLE_MAP_SIZE. Together
with validation in mapAsync in dawn native, we can ensure that the
size parameter deserialized in wire server is a valid actual size.
When using default size with dawn wire, the actual size is computed
by wire client, and WGPU_WHOLE_MAP_SIZE shall never be passed to server.

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 on Windows 10
    • Metal on macOS and iOS
    • Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
    • OpenGL as best effort where available
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
