Add tests for lazily initializing indirect buffers

This patch adds the end2end tests on the buffer lazy-initialization on
indirect 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 indirect buffers.

This patch also enables all the tests with write-only storage textures
on Metal, Vulkan and OpenGL with SPVC parser as these tests only fail
on D3D12 backends.

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
