Summary:
**Context/Summary:**
- StopWatch enable stats even when `StatsLevel::kExceptTimers` is set. It's a harmless bug though since `reportTimeToHistogram()` will not report it anyway according to https://github.com/facebook/rocksdb/blob/main/include/rocksdb/statistics.h#L705
-  https://github.com/facebook/rocksdb/pull/11288 should have removed logics of setting `record_read_stats = !for_compaction` as we don't differentiate `RandomAccessFileReader`'s stats behavior based on compaction or not (instead we now report stats of different IO activities including compaction to different stats). Fixing this should report more compaction related file read micros that aren't reported previously due to `for_compaction==true`

Test Plan:
- DB bench pre vs post fix with small max_open_files

Setup command
`./db_ bench  -db=/dev/shm/testdb/ -statistics=true -benchmarks=fillseq -key_size=32 -value_size=512 -num=5000 -write_buffer_size=655 -target_file_size_base=655 -disable_auto_compactions=true -compression_type=none -bloom_bits=3`

Run command
`./db_bench --open_files=1 -use_existing_db=true -db=/dev/shm/testdb2/ -statistics=true -benchmarks=compactall -key_size=32 -value_size=512 -num=5000 -write_buffer_size=655 -target_file_size_base=655 -disable_auto_compactions=true -compression_type=none -bloom_bits=3`

Pre-fix

Post-fix (with a higher `rocksdb.file.read.compaction.micros` count)
```
