stmtbundle: include TRIGGER related dependencies

[yuzefovich]

Currently, we don't include TRIGGER functions nor tables they might modify in the stmt bundle. For example,

CREATE TABLE t1 (k1 INT PRIMARY KEY, v1 INT);

CREATE TABLE t2 (k2 INT PRIMARY KEY, v2 INT);

CREATE FUNCTION f() RETURNS TRIGGER LANGUAGE PLpgSQL AS $$
  BEGIN
    INSERT INTO t2 SELECT (NEW).k1, (NEW).v1;
    RETURN NEW;
  END
$$;

CREATE TRIGGER foo AFTER INSERT ON t1 FOR EACH ROW EXECUTE FUNCTION f();

EXPLAIN ANALYZE (DEBUG) INSERT INTO t1 VALUES (1, 10);

neither trigger foo, nor UDF f, nor table t2 are included in the bundle.

This is probably related to #138022.
