Use native attribute to read mocks

[pierredup]

This allows to import mock classes when using the Phake\Mock attribute

use Some\Awesome\CoolInterface;

class Foo
{
    #[\Phake\Mock(CoolInterface::class)]
    private $mockProperty;
}

This builds on top of #318 to have access to the Phake\Mock attribute class.

Thanks :) Same as your previous PR. Could you please rebase it to 4.4 branch.

Would it be possible to keep a test where class is null ?

[pierredup]

I think these 2 test cases still cover this scenario where class would be null
