PHP 8.5: properly cast objects to int in UvDriver

[Fneufneu]

UvDriver does not work in PHP 8.5 and give errors:

Object of class UVTimer could not be converted to int ...UvDriver.php on line 180
Object of class UVSignal could not be converted to int ...UvDriver.php on line 196
Object of class UVPoll could not be converted to int ...UvDriver.php on line 162
Fatal error:  Uncaught AssertionError: assert($w instanceof StreamCallback) in ...UvDriver.php:168

So i simply replaced (int) by spl_object_id()
