[dawn][emscripten] Update public import/export APIs.

- Adds new APIs in library_webgpu.js as per
  https://docs.google.com/document/d/1WK6M1ZkFrEwa1Cjx8Tjq1x68ZWt8u1_tUidg_mvNs1Q/edit?usp=sharing&resourcekey=0-fiEZvGkjpsQqLsrcfNqB-w
- Shuffles EventSource in class hierarchy to allow for
  easier defaulting and passing of "parents". Also required
  shuffling around "delete" call since multi-inheritance means
  the "this" pointer cannot be used for deletion.
- Renames/move internal implementation details into
  Internals subobject namespace.
- Removes bufferWrapper concept and store the unmap
  callbacks in a separate table to keep the internal
  table simple for the API.
- Removes makeCheckDefined since it's no longer needed given
  that buffers onUnmap are tracked separately.
- Adds a way to specify __deps for helpers.

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.
