Remove option to enable/disable depth projection from ui

[Wumpf]

What

• Part of: Replace EditableAutoProperties with a SpaceView component default system #5067
• Based on (for merge conflict reduction): Expose Colormap component for DepthImage, depth image colormap now used outside of reprojection #6549

This will soon be handled by enabling/disabling visualizers instead.
A sideeffect of this is that the option to change the depth image colormap also shows up in 2D views (as it should). But we're going to do a pass over how this ui is generated soon anyways which would have also caught this.
