Add PhpDocPropertySorterFixer

[kilya11]

Sorts @property annotations by name in PHPDoc blocks alphabetically within groups separated by empty lines.

Original:

/**
 * @property int $second
 * @property string $first
 *
 * @property array $third
 * @property bool $fourth
 */

fixed:

/**
 * @property string $first
 * @property int $second
 *
 * @property bool $fourth
 * @property array $third
 */
