Bug 1470545: Add chromeonly "shadowrootattached" event for devtools. r=smaug

Summary:

document.addEventListener("shadowrootattached", e => {
  // Do stuff with composedTarget.
});

I didn't bother to add tests for the event itself since this is going to get
tested in bug 1449333, but I can look into writing a chrome mochitest if you
want.

Test Plan: See above.
