### What problem does this PR solve?
Support materialized view query rewriting by join eliminate when mv use more
table than query
Such as mv def is as following
```sql
CREATE MATERIALIZED VIEW mv_test
BUILD IMMEDIATE REFRESH COMPLETE ON MANUAL
DISTRIBUTED BY RANDOM BUCKETS 2
PROPERTIES ('replication_num' = '1')
AS
select l_shipdate, l_linenumber, l_partkey, l_orderkey, o_orderkey,
o_partkey, o_suppkey, o_custkey, ps_partkey, ps_suppkey, ps_availqty,
ps_supplycost from lineitem_1
left join orders_1
on o_orderkey = l_orderkey
left join partsupp_1
on ps_partkey = l_partkey and ps_suppkey = l_suppkey
```
if query is as following, it can be rewritten successfully by mv above
though query has less tables than materialized view `mv_test`.
```sql
select l_shipdate, l_linenumber, l_partkey, l_orderkey
from lineitem_1
left join partsupp_1
on ps_partkey = l_partkey and ps_suppkey = l_suppkey
```
Because the materialized view `mv_testis` built on base tables that have
specific primary key and foreign key constraints, the `orders_1` table can be
eliminated (through join elimination) without causing incorrect query results.
Therefore, the aforementioned query can be transparently rewritten using
`mv_test`. This mechanism and rule for join elimination are consistent with the
principles of ELIMINATE_JOIN_BY_FK(Eliminate Join by Foreign Key) and
ELIMINATE_JOIN_BY_UK(Eliminate Join by Unique Key)
```sql
alter table orders_1 add constraint pk primary key(o_orderkey)
alter table lineitem_1 add constraint fk foreign key (l_orderkey) references
orders_1(o_orderkey)
```
