Fix #529: Player falls off his bike when it is teleported

[iManGaaX]

Summary

When a vehicle is moved more than 10 units in one go, CVehicleSA::OnChangingPosition repositions its wheel collision points so the physics doesn't keep working with the ground contacts of the old location; that handling only covered CAutomobile (base vehicle type 0), but bikes (CBike = 9, CBmx = 10) keep their own copy of those colpoints; so after a far teleport a bike was still using the contacts of its old position, which made the physics go wild and knock the rider off

Changes

• CBikeSA.h: m_anWheelColPoint is declared as CColPointSAInterface[4] instead of raw bytes (same size and offsets, the sizeof == 0x814 assert still guards the layout)

• CVehicleSA.cpp: reposition the bike wheel colpoints on big moves, exactly like it is already done for automobiles

Closes #529.
