Merlin Mao baf22b4ee6 Add IteratorTraceExecutionResult for iterator related trace records. (#8687)
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`.

Merlin Mao ff8953380f Add iterator's lower and upper bounds to TraceRecord (#8677)
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`.

Merlin Mao d10801e983 Allow Replayer to report the results of TraceRecords. (#8657)
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.

Merlin Mao f58d276764 Make TraceRecord and Replayer public (#8611)
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.
