IVGCVSW-4317 Implement the Profiling Context Initialisation

* Call CreateBackendProfilingContext on each backend from Runtime passing
  an instance of the BackendProfiling interface.
* Modify the signature of CreateBackendProfilingContext to remove const
  and return a shared_ptr to BackendProfilingContext
* Add concrete BackendProfiling class.
* Store BackendProfilingContexts in Profiling service.
