This is a preparation for doing a similar change to JSTypedArrays to
be able to finally access huge ArrayBuffers with TypedArrays. This CL
itself improves the performance of DataViews, sometimes to be even
faster than TypedArrays now. On the test case[1] we go from

  testDataViewGetUint8: 711 ms.
  testUint8Array: 654 ms.
  testDataViewGetUint16: 801 ms.
  testUint16Array: 649 ms.
  testDataViewGetInt32: 699 ms.
  testInt32Array: 648 ms.
  testDataViewGetFloat64: 701 ms.
  testFloat64Array: 650 ms.

to

  testDataViewGetUint8: 622 ms.
  testUint8Array: 656 ms.
  testDataViewGetUint16: 634 ms.
  testUint16Array: 656 ms.
  testDataViewGetInt32: 629 ms.
  testInt32Array: 655 ms.
  testDataViewGetFloat64: 631 ms.
  testFloat64Array: 661 ms.

so the performance improves by up to **20%**.

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.

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.
