[BUG]: Form bind not usable with Radio element

[noone-silent]

Describe the bug Based on how bind works and checks for elements, radios do not work (https://github.com/phalcon/cphalcon/blob/v4.1.3/phalcon/Forms/Form.zep#L160) This bug could affect multiple things like Tag::setDefault() for example.

To Reproduce The problem with radios is, that they need to be added with a different name, else they overwrite themself.

$entity = new \Vokuro\Models\Users();
$form = new \Vokuro\Forms\UsersForm($entity);
$form->remove('banned');
$form->add(new Radio('r0', ['name' => 'banned', 'value' => 'no']);
$form->add(new Radio('r1', ['name' => 'banned', 'value' => 'yes']);

// Simulate POST data
$form->bind(['banned' => 'yes'], $entity);

echo $entity->banned; // displays null or default value

Expected behavior The form should bind the value to the correct element.

Workaround The current workaround for this problem is the following. Maybe the workaround should be done automatically and not rendered ever.

$entity = new \Vokuro\Models\Users();
$form = new \Vokuro\Forms\UsersForm($entity);
$form->remove('banned');
$form->add(new Radio('r0', ['name' => 'banned', 'value' => 'no']);
$form->add(new Radio('r1', ['name' => 'banned', 'value' => 'yes']);

// Workaround (can apply filters here etc. (should not be rendered)
$form->add(new Hidden('banned'));

// Simulate POST data
$form->bind(['banned' => 'yes'], $entity);

echo $entity->banned; // displays yes now

I think the Problem also exists with Checkbox

Another issue regarding this bug: The radio which matches the entity value will never automatically be checked

Another bug I just found. Form bind doesn't work for array elements too:

        $employee = new Select(
            'employees[]',
            Users::getForDropdown(),
            [
                'class' => 'form-control',
                'required' => 'required',
                'multiple' => 'multiple',
                'size' => 5,
            ]
        );
        $employee->setDefault($entity->employees);

Then in Form::bind https://github.com/phalcon/cphalcon/blob/4.2.x/phalcon/Forms/Form.zep#L203 Obviously there is no key with the name employees[]

The solution for something like this, would be a new option entityKey which you could set to employees in this case. Then in the corresponding line, it should check if this option is set and use this key instead. This would also solve the radio problem from above.
