Add new error class `QueryCanceled` which will be raised when canceling statement due to user request (#31235)
This changes `StatementTimeout` to `QueryCanceled` for PostgreSQL.
In MySQL, errno 1317 (`ER_QUERY_INTERRUPTED`) is only used when the
query is manually cancelled.
But in PostgreSQL, `QUERY_CANCELED` error code (57014) which is used
`StatementTimeout` is also used when the both case. And, we can not tell
which reason happened.
So I decided to introduce new error class `QueryCanceled` closer to the
error code name.
