Clément Foucault 417ffa8f54 Fix #137097: Cycles: No occlusion with Grease Pencil in the viewport
This was caused by missing depth of objects.
The old implementation was relying on the external engine
to provide the correct depth of the objects.
This patch does exactly this.

The downside is that, if overlays are present, the prepass
will be also drawn by the overlay engine.
