Jiawei Shao 80f927d763 Implement buffer lazy initialization before writeBuffer
This patch implements buffer lazy initialization before writeBuffer():
if the buffer is not initialized and writeBuffer() doesn't cover the
whole buffer, the buffer will be cleared to 0, otherwise the buffer
shouldn't be cleared.

This patch also introduces a toggle LazyClearBufferOnFirstUse for the
development of buffer lazy initialization: before buffer lazy
initialization being completely supported, all the related code will
only be enabled behind this toggle to prevent the buffers with valid
content being unexpectedly cleared.

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
