Add tests for lazy initializing vertex and index buffers

This patch adds the end2end tests on the buffer lazy-initialization on
vertex and index buffers. In the last patch we have already supported
buffer lazy initialization on all the buffers used in a render pass and
compute pass, so in this patch we just need to add tests to ensure
buffer lazy initializations run as we expect on vertex and index
buffers.

This patch also adds the missing checks on all the BufferZeroInitTests
to ensure the buffers are not lazily initialized when we validate if
their data is all set to zero in these tests.

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
