Problem/Motivation

\Drupal\views_ui\Form\Ajax\ViewsFormBase::getForm() relies on very odd PHP behaviour that is fixed in PHP 8.

This is happening because of this behaviour change in PHP 8.0 - https://3v4l.org/TJ2cb.

This change in behaviour in PHP 8 is explained with this RFC: https://wiki.php.net/rfc/string_to_number_comparison. TL;DR, PHP 8 has adopted changes to how string to integer comparisons should be handled and no longer type juggling a string to a numeric equivalent before comparison.

Steps to reproduce

if (isset($view->form_cache) && $view->form_cache['key'] != $key) {
to
if (isset($view->form_cache) && $view->form_cache['key'] !== $key) {
and run core/modules/views_ui/tests/src/Functional/FilterUITest.php

see https://dispatcher.drupalci.org/job/drupal_patches/63999/

Proposed resolution

Don't duplicate the use $key and change to !==

Remaining tasks

User interface changes

API changes

Data model changes

Would it be better to also rename $key as $form_key?
