Remove InputMethodManager.ImeThreadFactory, which is unused

InputMethodManager.ImeThreadFactory was originally introduced to fix
Bug 147331480 but all its usages were already removed by a subsequent
CL [2], which somehow forgot to remove this class.

Anyways, this class is definitely unused right now hence it should be
safe for us to remove it.
