ReferenceError: __dirname is not defined when building as ES 6 module using node 14

[kjlubick]

I am trying to build CanvasKit using ES 6 modules as a result of the discussion in #12952

However, when I try to run my test code in node.js, I see the error

ReferenceError: __dirname is not defined

Which comes from the generated JS code around here:

if (ENVIRONMENT_IS_NODE) {
  if (ENVIRONMENT_IS_WORKER) {
    scriptDirectory = require('path').dirname(scriptDirectory) + '/';
  } else {
    scriptDirectory = __dirname + '/';
  }

I talked with @RReverser and from that conversation:

If updating to 2.0.10 still doesn't work, then it's Emscripten bug that needs to be fixed (it probably assumes that Node.js never runs ES6 modules, which it does now and needs a feature detection to choose between __dirname and import.meta.url)

(I made sure I was using 2.0.10 and the issue still persists).

Looks like others have noticed this too: #11792

@sbc100 Oh yeah, looks like this is a duplicate then.
