In `FakeAsyncZoneSpec`, there are several variables and APIs to identify different times, and the names are confusing, in this commit, they are renamed for more clear understandings. 1. currentTickTime, the tick millis advanced. 2. getFakeBaseSystemTime(), return the fake base system time. 3. setFakeBaseSystemTime(), set the fake base system time. 4. getRealSystemTime(), get the underlying native system time.
