refactor: update dependencies, drop TAP

This updates our dependencies. I was also recently made aware of Node's
support for custom reporters thanks to rluvaton, which was not available
when I first began working on the extension. This moves over to them and
makes a bunch of assorted fixes found on the way. Some notable ones:

- We now use `pretty-format`, the same library used in Jest, to
  format objects for diff comparison.
- Console output is no longer associated with specific test cases. This
  is not possible to do with current APIs, since the test reporters
  always get events asynchronously, so a test may not even be 'started'
  when we intercept a `console.log`. We did some best effort stuff here
  before, but it was very poor.

  (It would be better to use async_hooks to handle tests running in
  parallel, but there's (perhaps rightly) not a point in which we can wrap
  test methods to do that without trying to money-patch modules.)

- There's a new `nodejs-testing.verbose` config option folks can use to
  get raw reporter information in the Test Results output to aid in
  issue reporting.

- The test runner might be a bit more speedy since our worker no longer
  imports the large `tap` module.

- I fixed an issue that may have resulted in test cases not reporting
  results in spite of correct console output.

- You can now choose between a couple of different simple output styles
  for the Test Results console using the `nodejs-testing.style`
  config option.
