Breaking change: use addEventListener rather than setting window.onerror

* Generally simplifies error handling in browsers
* Makes Jasmine's own integration tests easier to debug
* Stack traces will be provided for more global errors
* ... but less error information will be provided in some browsers if the
  error comes from a file:// URL (use `npx serve` or similar instead)
* Jasmine will no longer override existing onerror handlers in browsers
* Setting window.onerror will no longer override Jasmine's global error
  handling (use jasmine.spyOnGlobalErrors instead)
