testharness.js: allow_uncaught_exception in Deno

In Deno uncaught errors and unhandled rejections that are not
"preventDefault"'ed cause the runtime to exit with a non-0 status code.
Node has similar behaviour for unhandled rejections.

This commit adds support for these runtimes running tests that have
allow_uncaught_exception enabled by calling preventDefault on error
events when allow_uncaught_exception is enabled.

The primary motivator is that this would allow Deno to run reportError
tests.
