IVGCVSW-4455 Add an Activate and Deactivate control packet to the protocol

 * Add Activate/Deactivate command handlers
 * Add IReportStructure, INotifyBackends single function interfaces
 * Add overrided mechanism to report structure in Runtime.cpp
 * Add overrided mechanism to notify backends in ProfilingService.cpp
 * Add optional IReportStructure argument to ProfilingService constructor
   for use in ActivateTimelineReportingCommandHandler
 * Refactoring and tidying up indentation
 * Removal of unused code in ProfilingUtils.cpp and ProfilingService.cpp
 * Added GatordMock end to end test
 * Fixed an issue with SendCounterPacket sending duplicate packets
 * Fixed an issue with DirectoryCaptureCommandHandler handling of Optional
