Draws the terrain into reflection-probe cube faces. Create once per
(context, system) and register draw via
ReflectionProbeCapturePass.addExternalDraw. Owns one small uniform per
(probe slot, face) — the capture pass encodes all faces before the queue
submits, so a shared buffer would be overwritten by the last face.
