feat: add rw_internal_tables

[hzxa21]

I hereby agree to the terms of the RisingWave Labs, Inc. Contributor License Agreement.

What's changed and what's your intention?

Add rw_internal_tables to show internal table information.

Motivation:
Currently the only way to display internal table information via SQL is show internal tables. However, since we cannot join show internal tables, some information is hard to fetch. For example, we don't have a way to associate SST information (e.g. delete_ratio) with internal table name.
