[tint][sem] Make Function::AncestorEP return EP for EP

This simplifies a few parts of the code that had to handle entry points
specially because entry points weren't ancestors of themselves. Change
the name to CallGraphEntryPoints to better reflect the semantic.

The WGSL and HLSL AST printers empty line separation logic is updated
slightly to avoid all the end2end expectations changing. However due to
some structures not being output in HLSL (storage and uniform ones)
there are still noop expectations changes included.

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.
