Refactor SubmodelRepository FileHandling Methods into SubmodelService (

eclipse-basyx#244) * Move FileRepository interface/implementations to Common * Add file handling methods to SubmodelService API * Move file related tests from RepositorySuite to ServiceSuite * Refactor SubmodelRepo to use file handling logic from Service * Fix name typo in MongoDBFileRepository * Implement /attachment endpoints to the SubmodelServiceHttpController * Modify injection method of FileRepository in SubmodelServiceFactory
