  Properly implement TYPE_TRAITS for SpeechSynthesisErrorEvent
https://bugs.webkit.org/show_bug.cgi?id=305306

Reviewed by Chris Dumez.

Normally event class wrappers are created through
EventFactory::toJSNewlyCreated(Ref<Event>&&) which uses interfaceType()
instead of the TYPE_TRAITS mechanism.

However, there's another code path generated by the bindings for
subclasses if there's no longer a cached wrapper which is why
SpeechSynthesisErrorEvent needs TYPE_TRAITS. I could not figure out
with Claude AI how to test that code path however, but it seems better
if it ends up doing the correct thing.

I discovered this while making more of the TYPE_TRAITS isX() methods
private and final, which explains the other changes made here.
