Feature: #93835 - AddErrorForProperty function for AbstractValidator

See Issue #93835

Description

When validating Extbase models, it could be helpful to assign the encountered error to a certain property. This is already possible by using $this->result->forProperty($propertyPath)->addError($error);. This method however is cumbersome and requires knowledge about the result object. To ease the pain for developers, a convenience method addErrorForProperty is now available.

Use it like this in a validator class:

public function isValid(): void
{
   // validation
   $this->addErrorForProperty(
      'object.property.name',
      $this->translateErrorMessage(
          'validator.errormessage',
          'my-ext'
      ),
      // tstamp_of_now_as_errorcode
      123456789
   );
}

Impact

The new method enables developers adding custom error messages to validation results of properties in a convenient way.
