[DomCrawler] fix the axes handling in a bc way

The previous fix in #11548 for handling XPath axes was not backward
compatible. In previous Symfony versions the Crawler handled nodes
by holding a "fake root node". This must be taken into account when
evaluating (relativizing) XPath expressions.
check for the correct field type

HTML allow to define different form fields with the same name.
Imagine the following form:

    <html>
        <body>
            <form action="/">
                <input type="hidden" name="option" value="default">
                <input type="radio" name="option" value="A">
                <input type="radio" name="option" value="B">
                <input type="hidden" name="settings[1]" value="0">
                <input type="checkbox" name="settings[1]" value="1" id="setting-1">
                <button>klickme</button>
            </form>
        </body>
    </html>

Since the `FormFieldRegistry` can only handle one field per name, the
hidden field option is registered first before the radio field with
the same name is evaluated. Thus, the `FormFieldRegistry` returns an
`InputFormField` instance on which the `addChoices()` method can not
be called.
