Revert "[tint] Allow multiple entry points on the way from SPIR-V to WGSL"

This reverts commit 15f1e088a6824032cb13e256fe647e1d1527e09c.

Reason for revert: New test is failing/very flaky on CI and CQ, e.g.:
https://ci.chromium.org/ui/p/dawn/builders/ci/linux-clang-dbg-x64/b8707144039829783825/overview
[ RUN      ] SpirvReaderTest.MultipleEntryPoints
../../src/tint/lang/spirv/reader/reader_test.cc:661: Failure
Expected equality of these values:
  got
    Which is: failure: :16:1 error: a module with multiple entry points requires the AllowMultipleEntryPoints capability


Original change's description:
> [tint] Allow multiple entry points on the way from SPIR-V to WGSL
>
> All transforms along this path need to allow this capability.

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.
