Add finite timeout when synchronously terminating a service worker
https://bugs.webkit.org/show_bug.cgi?id=206325
<rdar://problem/58183380>

When this message reply is never received, it hangs everything.
If we haven't received verification that a service worker was terminated in 10 seconds, unhang everything
and tell the UI process to terminate the hanging service worker process. Continue handling messages during
these 10 seconds to hopefully turn a bad hang into no perceptible hang.
