Source map support

[badeball]

Per today, source maps aren't / can't be utilized. EG. when multiple step definitions match, we throw an error

Error: Multiple matching step definitions for: a step
  a step
  /a step/

.. while cucumber-js on the other hand, would throw something like

Multiple step definitions match:
  a step - features/step_definitions/cli_steps.ts:44
  /a step/ - features/step_definitions/cli_steps.ts:49

Furthermore, we just output dummy object in the JSON reports.

{
  "match": {
    "location": "not available:0"
  }
}

For reference, a PoC is avaliable in the branch source-map, but I'm waiting on evanw/esbuild#2218 to see if there's a smoother way of handling paths.

I'm guessing this is the same issue preventing this user from seeing the stack trace? cypress-io/cypress#23563

No, this is an entirely separate issue.
