Signature of abstract set hook not enforced #15140

Description

The following code:

<?php
interface I {
    public string $prop {
        set(int|string $value);
    }
}
class C implements I {
    public string $prop;
}

Currently does not produce an error, but should, because the implementing class does not satisfy the set(int|string) constraint.

Alternatively, explicitly specifying the set parameter in an abstract hook could be forbidden.
