Subject: IVGCVSW-4316 First draft of IBackendProfiling and
 IBackendProfilingContext

* Introduce two new backend profiling interfaces IBackendProfiling
  and IBackendProfilingContext.
* Add a mechanism to pull a context from a backend through IBackendInternal
* Update CL, Neon and Ref backends to return an empty profiling backend.
