[Enhancement]: Make autofill compatible with updated address fields display logic

[nielslange]

Describe the solution you'd like

In #47160, we've updated the address fields display logic. As a result of that, it's now possible that the Address line 2 field is hidden behind a link. In this case, autofill would not work for this field, as it only becomes available when the link is clicked. It's also not available in the DOM. This issue aims to enable autofill for the hidden Address line 2 field. In #47160 (review), @senadir mentioned the following:

One way we did autofill before was to render a hidden input (not sure if type hidden or just visually hidden) that would capture the autofill value, if captured, it will expand the actual field and fill it with that value.
