Patch 2/8: Implement core read/write operations for FSTestOSWrapper

Implements ReadFile() and WriteFile() and adds testing for them, since
they are needed to test each other, and pretty much all of the other
functions.

Also implements MkdirAll(), since it is needed in one of the testing
helpers, but does not include tests for it, since its tests require
other functions to be implemented. There is effectively a cycle in the
dependency graph between functions and their tests here that needs to
be broken to avoid a large monolithic patch.

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.
