feat(meta): show recovery cause when request is rejected

[BugenZhao]

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

What's changed and what's your intention?

When a DDL request is sent to the meta service which is under failure recovery, the failure cause will be included in the error message as well. Thanks to the progress made on #11443, all we need to do is to correctly return the error in meta.

ERROR:  Failed to run the query

Caused by these errors (recent errors listed first):
  1: gRPC request to meta service failed: Internal error
  2: The cluster is recovering
  3: gRPC request to stream service failed: Internal error
  4: Actor 4 exited unexpectedly
  5: Executor error
  6: Chunk operation error
  7: Division by zero

It's worth noting that after #12999, the message will rarely be seen by users as DROP is not rejected. But I guess it's still a good-to-have.

Also I don't find a way to test it in CI, as we cannot manually trigger a failure recovery now (or we have to depend on some unresolved bugs 😄, like the examples above). Perhaps we can introduce a debug-only statement to manually trigger one.
