feat(diff): add support for altered change stream states with recreating table

[sters]

If there is a recreating table diff which used on ChangeStream, the ChangeStream also recreated in the diff. But it makes a downtime on the ChangeStream.

As an alternative, I would suggest applying ALTER CHANGE STREAM twice.

  []string{
-       "ALTER CHANGE STREAM CS1 SET FOR T2",
+       "DROP CHANGE STREAM CS1",
        "DROP TABLE T1",
        "CREATE TABLE T1 (\n  id INT64,\n  name STRING(100) NOT NULL\n) PRIM"...,
        strings.Join({
-               "ALTER CHANGE STREAM CS1 SET",
+               "CREATE CHANGE STREAM CS1",
                " FOR T1, T2",
        }, ""),
  }
