[12.x] Add fakeFor and fakeExceptFor methods to Queue facade

[MrPunyapal]

This PR adds temporary testing methods to the Queue facade, following the same pattern established by the Event facade in #24230.

What's Added

New Queue Facade Methods:

• Queue::fakeExcept($jobsToAllow) - Creates a fake that allows certain jobs to be queued normally while faking others
• Queue::fakeFor($callable, $jobsToFake = []) - Temporarily replaces the queue with a fake during the execution of a callable
• Queue::fakeExceptFor($callable, $jobsToAllow = []) - Temporarily replaces the queue with a fake that allows certain jobs through during the execution of a callable

Benefits

Improved Test Isolation:

// Before: Fake affects the entire test
Queue::fake();
// ... test code ...
// Manual cleanup required

// After: Fake is automatically scoped
Queue::fakeFor(function () {
    Queue::push(new ProcessPayment);
    Queue::assertPushed(ProcessPayment::class);
}); // Original queue automatically restored

Selective Job Faking:

<?php
// Allow critical jobs to be queued normally, fake others
Queue::fakeExceptFor(function () {
    Queue::push(new CriticalSystemJob);  // Actually queued
    Queue::push(new EmailNotification);  // Faked
    
    Queue::assertNotPushed(CriticalSystemJob::class);
    Queue::assertPushed(EmailNotification::class);
}, [CriticalSystemJob::class]);
