fix: SUPPORTPATH may be undefined in some contexts

[paulbalandan]

Description
I'm updating phpstan-codeigniter to cater 4.7 and I'm hitting the following test error:

An error occurred inside PHPUnit.

Message:  Undefined constant "CodeIgniter\Test\SUPPORTPATH"
Location: /Users/paul/Workspace/phpstan-codeigniter/vendor/codeigniter4/codeigniter4/system/Test/CIUnitTestCase.php:127

Upon investigation, I learned that util_bootstrap.php defines SUPPORTPATH if tests/_support/ is an existing directory. Since I'm not using that, consequentially, that constant is not defined. This forces anyone to define a tests/_support/ directory which I find rather unconventional. However, my point is the class should not have a constant expression that relies on a conditionally defined constant.

Heh, I also discovered this the other day. I just created a local bootstrap.php . This also affects the project folder for configs. It's the same for the rector.

<?php
// utils/phpstan/phpstan-bootstrap.php

declare(strict_types=1);

defined('CONFIGPATH') || define('CONFIGPATH', realpath(__DIR__ . '/../../new_app/Config') . DIRECTORY_SEPARATOR);
defined('PUBLICPATH') || define('PUBLICPATH', realpath(__DIR__ . '/../../public') . DIRECTORY_SEPARATOR);

require __DIR__ . '/../../vendor/codeigniter4/codeigniter4/system/util_bootstrap.php';
