Added Object Overlap Overlay
- Added R32UI support to GPU_framebuffer
- Added R32U support to draw manager
- The overlay mode has a object data pass that will render 'needed' data to specific buffers so we can mix them together via a deferred rendering. In future will also add UV's and other data
- Overlap is implemented as an overlay so it could be used on top of the Scene lighted Solid mode (that will be rendered by Eevee.

- Added UInt R support to framebuffers
- Added the overlap as an overlay so should be reusable by other engines
(Scene lighted Solid mode)
Differential Revision: https://developer.blender.org/D3175
- Removed the depth pass as it will reuse the depth pass of the render
engine
- Used gl_FrontFacing to determine the facing
- Blender the result with the render engine result
Implemented the face orientation overlay for testing.
Overlay mode is only drawn when there are overlays to be rendered.
The overlay mode is rendered before the object mode.
