[Read Aloud] Pull notifications into a separate component

The previous data binding method was making it difficult to clear the
error messages from the language menu once it closed. So instead of
putting notification information in app.ts and passing it with data-
binding, I created a VoiceNotificationManager to notify listeners of
new messages. When the language menu opens, it registers as a listener,
and when it's closed, it deregisters. New listeners do get notified of
any in-progress downloads though because we always want to show those.

This will help with adding the other error messages in other places
for these same errors.
