ldb to display public unique id and dump work with key range (#10417)

Summary:
2 ldb command improvements:
1. `ldb manifest_dump --verbose` display both the internal unique id and public id. which is useful to manually check sst_unique_id between manifest and SST;
2. `ldb dump` has `--from/to` option, but not working. Add support for that.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/10417

Test Plan:
run the command locally
```
$ ldb manifest_dump --path=MANIFEST-000026 --verbose
...
