fix(pat autosubmit): Re-add support for autosubmit on non form elements.

Fix a problem introduces in Patternslib 9.9.7 where pat-autosubmit did
not work when not defined on a form or input element.

As a side effect, the submit event is now always invoked on the related
or nearest form of the element where pat-autosubmit was defined on. If
that element is not a form element a related (input.form) or the nearest
parent form is searched and the submit event invoked upon.
