   ## Proposed changes
   this is brought by https://github.com/apache/doris/pull/33800
   if mv is partitioned materialzied view,
   the data will be wrong by using the hited materialized view when the 
paritions in related base partiton table are deleted, created and so on.
   this fix the problem.
   
   if **SET enable_materialized_view_union_rewrite=true;** this will use the 
materializd view and make sure the data is corrent
   if **SET enable_materialized_view_union_rewrite=false;** this will query 
base table directly to make sure the data is right
