AlternativeTextClient::dismissDictationAlternativeUI is never called. It hasn't been touched in a long time, so it looks more like dead code than part of a plan in progress.

I do not know much about this code, so if you are aware of a reason to keep this function, please tell.
This function can be removed, since dismissal of both correction and dictionary alternative is done by WebAlterantiveTextClient::dismissAlternative() in both WK and WK2.
