AutoComplete: Enter does not submit form

[carldenigma]

Describe the bug

There's an issue with the AutoComplete component that affects native behaviour of input fields and form submission.

When attempting to submit a form using the 'Enter' key, the AutoComplete component captures the action and prevents the default behaviour, even when no overlay panel option is in focus.

To improve accessibility and align the AutoComplete component with native browser behaviour, it should not prevent the default action in this scenario. Instead, hitting 'Enter' on an input field should propagate to submitting the form.

When a overlay option foes have focus then 'Enter' should select the focused option rather than submitting.
