Converts the 21 per-level Usetup*Z stage-setup files to PC layout,
appending rows to the same pccg.bin/manifest sidecar as d69_emit.py.
Delta-relocates the 8 pointer-widened sub-tables (header 40->80B,
waypoint/waygroup/PathRecord/AIListRecord/PadRecord/BoundPadRecord/pname)
and byte-swaps the s32 ID/offset fields. propDefs left as an opaque
relocated passthrough for now (D88.4).
