[Autofill] Better sectioning for hidden fields.

Sometimes we have multiple sections on a form, but only the first one
is visible, and the next one will appear as the user is interacting
with the page. Currently, as a general rule, we ignore hidden fields
and never start a new section on one. This rule does not apply for
this case.

Example:

A hidden billing address section after a shipping one which appears
if the user has different addresses for billing and shipping.

Solution:

Change the general rule so that:

If current field is a hidden one, start a new section if two
following fields are seen in the previous section.

Also, keep the status of the already seen visible fields. When
back to the visible fields, assume that the hidden section
never existed. Depending on the field types, decide if the visible
field belongs to a new section or it belongs to the previous
visible section.

Tests adjusted, one test added/149.

[AF] optional callback for __gCrWeb.fill.setInputElementValue

Replaces an unused boolean argument with an optional callback that
indicates whether the input element's value was changed.
This callback is used to mark elements as autofilled only when the value
has actually changed. This fixes cases where a <select> element is marked
as autofilled while its value hasn't actually changed from its default
value. e.g., www.crutchfield.com
