ApproximateActors: add FMeshApproximationSettings::bEnableSimplifyPrePass option, default true, and implement in ApproximateActors impl. This does a fast-collapse down to a multiple of the target triangle count (or 1m tris in tolerance-mode). This reduces simplification time in HLOD builds for small city from 4-5m to 1m in some of the worst blocks.
ApproximateActors: add FMeshApproximationSettings::bEnableParallelBaking, default true, and implement in the ApproximateActors Impl. This allows the photocapture step to proceed at the same time as the mesh generation, which shaves 30-40s off every HLOD build, but increases memory requirements.
