fix(ngAria): trigger digest on ng-click via keypress, pass $event to expression

Minor improvement to ng-click directive from ngAria. Now, if bindings are updated
during the click handler, the DOM will be updated as well. Additionally, the $event
object is passed in to the expression via locals, as is done for core event directives.

Closes #10442
It would be better to check `attr.ngKeypress` to account for the several variations (`data-ng-keypress`, `x-ng-keypress`, `ng:keypress`, `ng_keypress` etc).
(Especially the `data-` prefix, which isn't uncommon.)
