Stop passing a PassRefPtr to dispatchEvent()
https://bugs.webkit.org/show_bug.cgi?id=151158

Reviewed by Alex Christensen.

Stop passing a PassRefPtr to dispatchEvent() because:
1. PassRefPtr is legacy and should no longer be used
2. We don't actually transfer ownership of the Event to the callee

Pass a C++ reference instead.
