Summary:
Trace file V2 added lower/upper bounds to `Iterator::Seek()` and `Iterator::SeekForPrev()`. They were not used anywhere during the execution of a `TraceRecord`. Now they are added to be used by `ReadOptions` during `Iterator::Seek()` and `Iterator::SeekForPrev()` if they are set.
Added test cases in `DBTest2.TraceAndManualReplay`.

Summary:
`Replayer::Execute()` can directly returns the result (e.g, request latency, DB::Get() return code, returned value, etc.)
`Replayer::Replay()` reports the results via a callback function.
New interface:
`TraceRecordResult` in "rocksdb/trace_record_result.h".
`DBTest2.TraceAndReplay` and `DBTest2.TraceAndManualReplay` are updated accordingly.
