Both Input Events Level 1 and Level 2 declare that InputEvent.data should be
set to inserting string only on TextEditor when InputEvent.inputType is
"insertFromPaste", "insertFromPasteAsQuotation", "insertFromDrop",
"insertTranspose", "insertReplacementText" or "insertFromYank".
Currently, we support only "insertFromPaste", "insertFromDrop",
"insertReplacementText". Therefore, this patch makes TextEditor set
EditorBase::mEditActionData::mData only for them (and the instance is not
HTMLEditor's).
