refactor(connector): make ConnectorError a wrapper of anyhow::Error

[BugenZhao]

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

What's changed and what's your intention?

Make ConnectorError a wrapper of anyhow::Error without implicit casting, so that developers are forced to provide default or ad-hoc context messages when doing conversion.

Check the documentation on def_anyhow_wrapper macro for the motivation and the design.

This is another attempt to resolve #15031 (comment).
