[12.x] Fix serialization issue with PHP property hooks

[Sajid-al-islam]

Fixes #57357

Fixes serialization errors when using PHP 8.4 property hooks in Eloquent models. When models with property hooks a serialized, Laravel throws: serialize(): "property_name" returned as member variable from __sleep() but does not exist.

Property hooks create virtual properties without actual storage. The current __sleep() uses get_object_vars() which includes these virtual properties, causing serialization to fail.

Solution: Changed get_object_vars($this) to get_mangled_object_vars($this) in Model::__sleep(). This only returns properties with actual storage, excluding virtual property hooks.

Tests: Added comprehensive coverage in EloquentModelPropertyHooksTest.php for getter hooks, setter hooks, multiple hooks, mixed properties, and queue scenarios.
