Add API fuzzing config GQL types and models

New GraphQL types follow the structure of the SAST configuration types:
* CiConfiguration::ApiFuzzing::ScanModeEnum
* CiConfiguration::ApiFuzzing::ScanProfileType
* CiConfiguration::ApiFuzzing::Type

New models:
* Security::ApiFuzzing::CiConfiguration
* Security::ApiFuzzing::ScanProfile
