refactor(error): move RwError from common to frontend

[BugenZhao]

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

What's changed and what's your intention?

Move RwError from common to frontend, as all the usages of RwError except for the frontend crate have been eliminated after #14950. From now on, RwError will only act as a top-level error type in the entire codebase.

Massive amount of files have been touched, but the only change is to replace risingwave_common::error with crate::error. One can review this PR commit by commit to get it clear, or just focus on the changes in the following files:

• common/src/error.rs
• frontend/src/error.rs

To make the PR focused on a single stuff, the definition of ErrorCode is not touched. Future refactoring has been marked as TODO in the comments.
