vehicleSubSystems Phase 1: reconstruct + register the cluster-panel family

Browse Source 
Reconstruct the whole engineering-screen (MFD) subsystem cluster-panel system in
btl4gau2 (from the Ghidra decomp of BTL4OPT.EXE) and register the vehicleSubSystems
config primitive:

- Sub-gauges: AnimatedSubsystemLamp/AnimatedSourceLamp (OneOfSeveral + cooling/
  power connections), ScalarBarGauge (BarGraphBitMapScalar + generator-voltage
  connection), ConfigMapGauge, plus the 3 file-private GaugeConnection classes
  (@004c3134/31ec/3288 samplers).
- SubsystemCluster base (ctor builds ~11 child gauges across the MFD + engineering
  ports; Execute/dtor/frame-draw/enable helpers) + the 5 subclasses HeatSink/
  Myomer/Weapon/Energy/Ballistic (ctors + Executes).
- VehicleSubSystems::Make dispatcher (@004cbaf0): per-subsystem factory keyed on
  classID (HeatSink 0xBC3 / Myomer 0xBC6 / Energy 0xBC8,0xBD4 / Ballistic
  0xBCD,0xBD0), placed via the 12-row aux-screen geometry table, + registered in
  BTL4MethodDescription[].

SAFE + gated: gauges only build under BT_DEV_GAUGES/pod, and until Phase 2
populates the subsystem aux-screen field (subsystem[0x1dc]) the Make hits its
"aux screen = zero" skip -> combat untouched.  Two minor children deferred as
marked NULLs (SegmentArc270 recharge dial + BitMapInverseWipeScalar eject wipe --
their ctors are btl4gaug placeholders).  Raw-offset subsystem reads (0x1dc/0x1e0/
0x1e4/0x31c/0x334/0x364/0x43c...) marked BEST-EFFORT pending Phase 2.
