Summary:
All/most trace related APIs directly use `SystemClock*` (https://github.com/facebook/rocksdb/pull/8033). Do the same in `TraceExecutionHandler`.

Summary:
- Allow to get `Valid()`, `status()`, `key()` and `value()` of an iterator from `IteratorTraceExecutionResult`.
- Move lower bound and upper bound from `IteratorSeekQueryTraceRecord` to `IteratorQueryTraceRecord`.
Added test in `DBTest2.TraceAndReplay`.

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.

Summary:
- Remove extra `;` in trace_record.h
- Remove some unnecessary `assert` in trace_record_handler.cc
- Initialize `env_` after` exec_handler_` in `ReplayerImpl` to let db be asserted in creating the handler before getting `db->GetEnv()`.
- Update history to include the new `TraceReader::Reset()`

Summary:
New public interfaces:
`TraceRecord` and `TraceRecord::Handler`, available in "rocksdb/trace_record.h".
`Replayer`, available in `rocksdb/utilities/replayer.h`.
User can use `DB::NewDefaultReplayer()` to create a Replayer to auto/manual replay a trace file.
Unit tests:
- `./db_test2 --gtest_filter="DBTest2.TraceAndReplay"`: Updated with the internal API changes.
- `./db_test2 --gtest_filter="DBTest2.TraceAndManualReplay"`: New for manual replay.
