[feature](nereids) Support basic aggregate rewrite and function rollup
using materialized view (#28269)
Add aggregate materializedviewRules for query rewrite.
it support the query rewrite as following:
def mv = "select lineitem.L_LINENUMBER, orders.O_CUSTKEY,
sum(O_TOTALPRICE) as sum_alias " +
"from lineitem " +
"inner join orders on lineitem.L_ORDERKEY = orders.O_ORDERKEY "
+
"group by lineitem.L_LINENUMBER, orders.O_CUSTKEY "
def query = "select lineitem.L_LINENUMBER, sum(O_TOTALPRICE) as
sum_alias " +
"from lineitem " +
"inner join orders on lineitem.L_ORDERKEY = orders.O_ORDERKEY "
+
"group by lineitem.L_LINENUMBER"
