The language server needs Torque compilation artifacts like
declarables for more advanced features. This CL moves the GlobalContext
into the LanguageServerData class when Torque compilation finishes, to
preserve all the compiler data.

Additionally, all declarables are split up by source id. This makes
providing all symbols of a file easier.

By accident I formatted anyfunc.js. However, since it's an improvement,
I don't want to undo it. I didn't change anything in the older tests
though, I only added new tests at the end.

They are added under the global scope object, as follows:

  {
    "memory": ...,
    "globals": {
      "global#0": ...,
      "global#1": ...,
      "global#2": ...,
    }
  }

We currently don't have any way to name globals in the wasm binary
format, but it is possible to extend the name section with these names
in the future.
