Some fast/table tests should wait for images specified via CSS url()

Some fast/table expect images specified via CSS url() specifier are loaded
before the test runner dumps the output, but it's actually not guaranteed. This
leads to test flakiness.

Currently all url() are written inline, so we can rely on the Document load
event. This CL adds resources/base.js which calls notifyDone when the event is
fired.
