fix($compile): ensure element transclusion directives are linked with comment element

This corrects a complicated compiler issue, described in detail below:

Previously, if an element transclusion directive contained an asynchronous directive whose template
contained another element transclusion directive, the inner element transclusion directive would be
linked with the element, rather than the expected comment node.

An example manifestation of this bug would look like so:

```html
<div ng-repeat="i in [1,2,3,4,5]">
  <div my-directive>
  </div>
</div>
```

`my-directive` would be a replace directive, and its template would contain another element
transclusion directive, like so:

```html
<div ng-if="true">{{i}}</div>
```

ngIf would be linked with this template content, rather than the comment node, and the template element
would be attached to the DOM, rather than the comment. As a result, this caused ng-if to duplicate the
template when its expression evaluated to true.

docs(ngSubmit): ngSubmit also works with the `data-action`/`x-action` attributes

The documentation states only the "action" attribute triggers this, which is incorrect. When using
the attribute "data-action" (as for AJAX control, attempting to bypass the "action" attribute but
still make it obvious what its for), Angular thinks this is also classified as "action" and
continues with the page submission.
