Print perf context for all benchmarks if enabled (#10396)

Summary:
If user runs `db_bench` with `-perf_level=2` or higher, db_bench should
print perf context after each of all benchmarks.

Or make `-perf_level` a per-benchmark switch.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/10396

Test Plan: ./db_bench -benchmarks=fillseq,readseq -perf_level=2
