Add Profiling Overlay

Can be activated at adding a QDebugOverlay in the frame graph to
identify which surface it should be renderer one (renders only
once on first branch that contains such a node).
Can be also activated on the forward renderer from Qt3DExtras.

- Shows information about FPS and number of
  jobs/renderviews/commands/vertices/entities/geometries/textures...
- Allows to toggle job and gl call tracing and open folder where
  trace files are stored
- Windows to show and dump glinfo and renderview/command details to the
  console
