/// 组件变更，增加和删除组件，及删除entity
/// 如果原型上没有要删除的组件，则自动忽略
/// 如果要增加的组件在源原型上存在，则直接替换
/// 和Query一样，可以get和iter，如果该原型可以查到，则会记录在本地源原型列表中
/// 要求entity的原型，必须在本地源原型列表中，这样保证有正确的写依赖
/// 根据删除时entity的原型，动态查找和创建删除后对应的原型
/// 删除组件会在源原型对entity进行标记删除，如果system后续迭代和查找是找不到的，但如果有引用，则引用还是可以继续读写。
/// 目标原型会立即添加新的条目，但该条目的entity是null，表示是看不到的。这时添加的组件，会立即写到目标原型对应的位置，等变更结束时，会将标记删除的entity，誊写到目标原型上，并修改entity。
/// 目标原型有可能和本system的原型重合，但由于alter是延迟的，也不会有引用被改写的问题
///
/// 最新： 计划使用执行图来保证，alter不会操作到正在读写的原型。 这样就不用处理各种多线程数据不一致的情况， 比如 entity 读有值， 但组件没有读到正确数据。
/// 每个system的run会根据依赖是否全部写完毕才开始执行，对应的就是一个ShareU32的wait_count数字减到0。
/// 每个system有自身状态ShareU8的run_state，初值为wait。system的run会先执行before，before会先同步world上原型数组的长度，同步后，修改自身状态ShareU8为running，执行完毕后改为ok。
/// 执行图在执行中， 收到A某system产生的原型创建的事件，此时该原型还为放入world上原型数组， 用该原型去匹配所有的system，返回：无依赖、读、写、目标写原型（alter会根据源原型写到目标原型，该目标原型也需要纳入写）。
/// 如果有依赖，则立即将wait_count加1，如果原wait_count=0表示已经开始执行，那么循环等待该system的run_state为running或ok。 这样，对该system要么看到该原型，要么看不到。
