logan buchy afc26a0f51 Prevent LevelEditorViewportClient draw on PIE in LevelEditorViewport ...

* This change addesses an issue which causes the LevelEditorViewportClient to render while PIE is active on the LevelEditorViewport. This results in a frame which is never displayed and therefore reduced rendering performance.
* The issue's root cuase is due to behaviour where the GameViewportClient and EditorViewportClient swap their stat flags when PIE is started on a selected LevelEditor sceneviewport - see FSceneViewport::SwapStatCommands.  When stat flags are present on the GameViewportClient before PIE is started, the EditorViewportClient will inherit the stat flags.  However, this has the side-effect of pushing a 'true' RealTime override onto ViewportClient.  This causes ViewportClient->IsRealtime() to return true.
* UEditorEngine::UpdateSingleViewportClient() is called by the UEditorEngine::Tick() each frame,  finds the EditorViewportClient->IsRealtime() to be true and triggers LevelEditorViewportClient->Viewport->Draw() even though there is no SceneViewport to display the render.
* The fix pushes a realtime override to disable realtime mode for the LevelEditorViewportClient when a PIE session is started that takes over the LevelEditorViewport and subsequently removes the override when PIE ends.

Removed dependencies that aren't needed by the modules that declare them. This is to help fix bad circular dependencies in the engine.
