IVGCVSW-3596 Register the dynamic backends in the BackendRegistry
* Added getter for the factory function in the DynamicBackend class
* Added new RegisterDynamicBackends method in utils class
* Added dynamic backend registration process in the Runtime class
* Added new dummy dynamic backend objects for testing
* Added unit tests for dynamic backend registration
* Added convenience methods to BackendId
