[emdawnwebgpu] Fix string-to-int tables with Closure, enable Closure in tests

Fix string-to-int tables by (1) making them library-level items that are
explicit dependencies (separate from $WebGPU) and (2) wrapping them to
prevent Emscripten from removing the quotation marks on the keys, that
signal to Closure that they shouldn't be minified.

This has the added benefit of Emscripten being able to eliminate tables
that are unused by the application.

Enable --closure=1 in Release builds, and add a test which explicitly
tests this. (The GetCompilationInfo tests also catch this.)

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.
