DeleteTextTransaction should have 3 factory methods. One is, simply to create an instance with a pair of offset and length. The others are, to create an instance for deleting a previous or next character at offset. The former was EditorBase::CreateTxnForDeleteText() and the latter was EditorBase::CreateTxnForDeleteCharacter(), but this patch creates DeleteTextTransaction::MaybeCreate() for the former, DeleteTextTransaction::MaybeCreateForPreviousCharacter() and DeleteTextTransaction::MaybeCreateForNextCharacter() for the latter.
