Skip getTableHandle call in information_schema.columns with table filter#18730

When reading `information_schema.columns` with a filter on table name (either `=` or `IN`), the code was doing `getRedirectionAwareTableHandle` call to check whether target table exists. However, the redirected tables are handled in `doListTableColumns` (also catching `TABLE_REDIRECTION_ERROR`), so the call inside `calculatePrefixesWithTableName` is redundant.
