What does code say about using #3 awg copper for the hots, #3 awg copper for neutral and # 8 awg copper for ground on a 135 ft run between the main and this 100 amp subpanel?

That would be the case assuming a 100% unbalanced load. With a balanced load and or line to line loads the current can go up will out exceeding the voltage drop recommendations.I will note that, although it is not a NEC violation, at 50 amps or greater you will be exceeding the recommended voltage drop with a #3.
