Change tint emission for multiple entry points.

Currently, if you provide an output file like `-o foo.hlsl` and the
given `wgsl` we change the name of the output file to inject the entry
point name (so you may get `foo.main.hlsl` output instead).

This behaviour is confusing, instead, if `-o` is provided but `--ep` is
not and there are multiple entry points, we emit an error and require an
entry point to be provided.

This does not effect emitting to stdout, you'll still get all of the
entry points emitted. It also does not require `--ep` if there is only a
single entry point in the WGSL file.

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.
