PHP : Set appropriate SCRIPT variables in $_SERVER superglobal

[mho22]

What is this PR doing?

Based on the issue #1090

When requesting a url, the current behavior is copying the value from REQUEST_URI to SCRIPT_NAME and SCRIPT_FILENAME $_SERVER variables.

It should actually be related to the PHP_SELF variable when handling request instead of REQUEST_URI when running code.

What problem is it solving?

To avoid a mismatch when using SCRIPT variables

Testing Instructions

const php = await NodePHP.load( '8.2, { requestHandler : { documentRoot : '/php' } } );

php.writeFile( 'php/index.php', "<?php echo json_encode($_SERVER);" );

const response = await php.request({
	url: '/',
	method: 'GET',
});

console.log( JSON.stringify( response.json, null, 2 );

This should display :

REQUEST_URI='/'
SCRIPT_NAME='/index.php'
SCRIPT_FILENAME='/php/index.php'
PHP_SELF='/index.php'

instead of currently :

REQUEST_URI='/'
SCRIPT_NAME='/'
SCRIPT_FILENAME='/'
PHP_SELF='/'

Let's also add a test to see what happens when the file is called test.php is in a subdirectory, e.g. /php/subdirectory/test.php

@adamziel I added the test you asked. Is it what you expected ?
