[DoctrineHelper] handle property type for custom doctrine type

[IndraGunawan]

fixed: #1002
replace: #1021

sample custom type

<?php

declare(strict_types=1);

namespace App\Doctrine\DBAL\Types;

use Cake\Chronos\Chronos;
use DateTimeImmutable;
use Doctrine\DBAL\Platforms\AbstractPlatform;
use Doctrine\DBAL\Types\ConversionException;
use Doctrine\DBAL\Types\DateTimeImmutableType;

class ChronosDateTimeType extends DateTimeImmutableType
{
    final public const CHRONOS_DATETIME = 'chronos_datetime';

    /**
     * {@inheritDoc}
     */
    public function convertToPHPValue($value, AbstractPlatform $platform): ?Chronos
    {
        if (null === $value) {
            return null;
        }

        $dateTime = parent::convertToPHPValue($value, $platform);

        return Chronos::instance($dateTime);
    }

    /*
     * ....
     */
}

this change will get convertToPHPValue function return type and set it as property type
if no return type defined on convertToPHPValue function then the property will not have any type hint

This looks good. A couple minor comments to improve readability.
