IVGCVSW-5879 Fix problems with using internal profiling from delegate.

* Pass through the value of m_EnableProfiling from Executenetwork to
  DelegateOptions.
* If internal profiling is enabled print it out from inside the delegate.
* Remove an unnecessary ProfilerImpl instance from WorkingMemhandle.hpp
* Remove an unnecessary parameter from TfLiteDelegateMainImpl in
  ExecuteNetwork.
