IVGCVSW-1955: Unify backend exceptions (wrap cl::Error)

* Added wrapper function around arm_compute::IFunction::run() that catches
  cl::Error and wraps it into an armnn::RuntimeException
* Added MakeWorkload template inside ClWorkloadFactory that catches
  cl::Error and wraps it into an armnn::RuntimeException
* Replaced cl::Error with armnn::RuntimeException in catch statements inside
  LoadedNetwork
