Core/Player: Added character templates

* Characters with predefined levels can be created
* Avaiable factions and classes can be configured
* Valid values for `factionGroup` in table `character_template_class` are 3 (Alliance) or 5 (Horde)
* Added new permission RBAC_PERM_USE_CHARACTER_TEMPLATES - has to be set, to allow the usage of the templates

Closes #13952
