Cleanup and simplify camera override API
- Harmonise the camera override 2D and 3D APIs - Switch to using Camera2D/3D nodes to provide override functionality. This makes for simpler code, gets rid of much of copy-pasted camera code and makes code that relies on current viewport camera such as VisibleOnScreenNotifiers and object picking work out of the box. - Make camera override code only accesible within DEBUG_ENABLED builds
