Keep support checks for stacked-deck columns.

A stacked-deck vehicle can retain unequal column offsets after leaving a ramp. In advance_precalc_mounts(), col_ramp starts from prt.precalc[1].z - prt.mount_z; when the destination has no ramp, the code does not reset it. It subtracts only the common ramp_offset, so a raised lower-deck column can remain above unsupported terrain.

level_vehicle() now skips the support checks that previously detected unsupported Z-levels and called displace_vehicle(). check_falling_or_floating() is not a replacement: it stops after any lowest column has support. Check the lowest structural part in each column and lower unsupported columns without restoring the old whole-level collapse behavior.

Review comment at @src/vehicle_move.cpp at line 2097:
Update the support handling in level_vehicle() to check the lowest structural
part in each stacked-deck column and lower only columns whose lowest part lacks
support. Preserve the existing per-column offsets from advance_precalc_mounts();
do not restore whole-level collapse behavior or rely on
check_falling_or_floating() as a substitute.
