Remove the direct use of BuilderImpl from TestHelperBase to cut down the amount of internal state management required by the tests, and removing confusing conflation between the BuilderImpl and Builder. This change removes the following methods from TestHelperBase: * CreateBuilder() * InjectFlowBlock() * CreateEmptyBuilder() * FlowNodeForAstNode() Tests now just use FromProgram() function for testing AST -> IR. The downside to the black-box testing is that the per-method granularity of the unit testing increases to whole FromProgram() granularity. However, my personal opinion is that this is more than offset by the lack of state leakage from the implementation to the 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.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- 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.
