Subject: [PATCH] Add column family info to TableProperties::ToString()

Summary: This is used at least by `sst_dump --show_properties`

Test Plan:
- default CF

```
  $ ./sst_dump --show_properties --file=./tmp-db/000007.sst | grep 'column family'
  column family ID: 0
  column family name: default
```

- custom CF

```
  $ ./sst_dump --show_properties --file=./tmp-db/000012.sst | grep 'column family'
  column family ID: 1
  column family name: col-fam-1
```

- no CF

```
  $ ./sst_dump --show_properties --file=./tmp-db/000017.sst | grep 'column family'
  column family ID: N/A
  column family name: N/A
```
