  Capture/Replay: Refactor shared context handling
  
  This is the initial CL to enable capture/replay of multi-context
  applications.
  
  This CL refactors FrameCapture and FrameCaptureShared to move much of
  the functionality into FrameCaptureShared, since most everything is
  shared by Contexts in the share group. For example, the setup of the
  majority of the GL objects is done in the new SetupReplayContextShared()
  function in the new $LABEL_capture_context_shared_frame001.cpp file. The
  setup is performed by (for example):
  
      void SetupReplay()
      {
          $LABEL::InitReplay();
          $LABEL::SetupReplayContextShared();
          SetupReplayContext2();
      }
  
  This performs the shared setup first, followed by the context-specific
  setup, which may reference shared objects careated by
  LABEL::SetupReplayContextShared().
  
  No re-capturing is required with this change, since the external APIs
  (i.e., SetupReplay()) are still the same.
  
  Bug: angleproject:5878
  Test: Manual MEC and replay of Magic Tiles 3, Candy Crush Soda Saga, Temple Run 2
