refactor(proto): replace TableRefId to uint32 for HashJoin

[BowenXiao1999]

What's changed and what's your intention?

Previously I use TableRefId (wants to keep consistent with Materialize Executor), but it's too inconvenient to write code.

Given that we wil remove TableRefId after Java frontend removed, replace it now.

Checklist

• I have written necessary docs and comments
• I have added necessary unit tests and integration tests

I'd propose replace all such occurrences to u32, if TableId is unique 🤣

Java is using TableRefId. So we have to change java code if do it now... But it indeed looks simple
