   ### What problem does this PR solve?
   Support explode table function rewrite when materialized view contains 
explode
   such as mv def is as following:
   ```sql
           CREATE MATERIALIZED VIEW mv_with_explode
           BUILD IMMEDIATE REFRESH COMPLETE ON MANUAL
           DISTRIBUTED BY RANDOM BUCKETS 2
           PROPERTIES ('replication_num' = '1') 
           AS
               select t.o_orderkey, t.l_orderkey, c2
               from 
               (
               select * from 
               orders
               left join lineitem on l_orderkey = o_orderkey
                where o_orderkey > 1
               ) t
               LATERAL VIEW explode_outer(t.o_array2) t1 as c2
               where o_orderkey > 2
   ```
   query is as following, this can be rewritten successfully by mv
   ```sql
               select t.o_orderkey, t.l_orderkey, c2
               from 
               (
               select * from 
               orders
               left join lineitem on l_orderkey = o_orderkey
                where o_orderkey > 3
               ) t
               LATERAL VIEW explode_outer(t.o_array2) t1 as c2
   ```
