Phone number verification event dispatcher

Might be a dupe of ✨ Phone number verification event dispatcher RTBC

The enabling/disabling of a verification depending on the entity and phone number context via event is implemented via \Drupal\sms\PhoneNumberVerification\Event\EntityPhoneNumberVerification::$shallSendVerification in v4.

The code component is no longer necessary as there is a specific service for that. Entity and phone number are provided as context.
