Write this to save map access performance and strengthen logical rigor

/**
   * {@inheritDoc IPhysicsManager.removeColliderShape }
   */
  removeColliderShape(colliderShape: LiteColliderShape): void {
    const { _eventPool: eventPool, _currentEvents: currentEvents, _eventMap: eventMap } = this;
    const { _id: shapeID } = colliderShape;
    for (let i = currentEvents.length - 1; i >= 0; i--) {
      const event = currentEvents.get(i);
      
      const isShape2 = event.index2 == shapeID;
      if (isShape2 || event.index1 == shapeID) {
        currentEvents.deleteByIndex(i);
        eventPool.push(event);

        // If the shape is big index, should clear from the small index shape subMap
        isShape2 && (eventMap[event.index1][event.index2] = undefined);
      }
    }
    delete eventMap[shapeID];
  }

Done.

Bad news: @luzhuang

• StaticCollider and StaticCollider shouldn't have trigger event or collision event, unit test logic is wrong
• The collider shape not set isTrigger = true, but trigger event fired
