IVGCVSW-4400 Backend Counter Registry Functionality

 * Adding BackendProfilingContext to the MockBackend
 * Made IBackendProfilingContext pure Virtual
 * Added UnitTest using MockBackend for testing Backend Counter Registration
 * Moved Registry of backend counters from Initialize() to AddBackendProfilingContext()
 * Added m_MaxGlobalCounterId to ProfilingService
 * Removed automatic registration of MockBack in BackendRegistry()
