Previously, we had an option on char/text fields called "onchange_on_keydown", which allowed to trigger the onchange while the user was typing (instead of when the field is blurred). It was notably used when typing a phone number in the sms composer, to warn the user that the phone number is invalid. This feature was lost during the port to OWL, this commit restores it.
