feat!: Integrate mantle v17

Integrates the new Mantle API:

• introduction of strong typed UniqueId (+ add formatting of new UniqueId type)
• Refactor route assignment via new route repository
• refactor content of entity/controller repositories to return shared pointers in getters
• adapt to renaming of enum values
• Assign enum values in MantleAPI structs explicitly (default is now kUnknown)
• replace usage of deleted test_utils.h with mocks from MantleAPI
• Delete Duplicate MockScenarioEngine (already present in MantleAPI)
• Refactor instantiation of Vec3/Orientation3 (only default constructor available now)
• add FindObjectByName() for convenience to algorithm_utils
