Adding Passback To DIC

• I have checked that another pull request for this purpose does not exist
• I wrote some tests for this PR

Small description of change:

I often find myself having to do the following:

use Phalcon\Di;
use Other;
use Another;

$di = new Di();

$di->set('name', function () {
   return $this->get(Other::class);
});

if (true) {
     $di->set(Other::class, Another::class);
}

This PR eliminates the extra steps by letting the service class instantiate through the DIC. I can now right the code as:

use Phalcon\Di;
use Other;
use Another;

$di = new Di();

$di->set('name', Other::class);
if (true) {
     $di->set(Other::class, Another::class);
}

Thanks
