-----------
Keep SpeechSynthesisUtterance wrapper alive when utterance is spoken multiple
times

rdar://114203537
Reviewed by Ryosuke Niwa.
In 266959@main and 266990@main, we make sure wrapper of
SpeechSynthesisUtterance is kept alive when it is being
processed. The "alive" period starts from when SpeechSynthesisUtterance is
handed to SpeechSynthesis via speak(), and
ends when SpeechSynthesisUtterance receives end events or
SpeechSynthesisUtterance is removed from SpeechSynthesis.
According to existing wpt test SpeechSynthesis-speak-twice.html, it is valid to
speak an utterance multiple times, i.e.
same utterance can be handed to SpeechSynthesis multiple times, so we should
make sure SpeechSynthesisUtterance is kept
alive until the last speaking is finished.
