### What problem does this PR solve? Currently, a materialized view can only have one PCT table. If the reference table has multiple partitioned tables and changes occur in non-PCT tables, even if only some partitions are modified, the materialized view must be fully refreshed, which is costly. Therefore, support for multiple PCT tables is needed, but with the following restrictions: - Only inner joins and unions (including UNION ALL) are supported. - In the case of unions, all base tables must be PCT tables; otherwise, the derivation fails. - The partition granularity across multiple PCT tables must align. For example: The following scenario is allowed: t1 has 2 partitions: [2020-01-01, 2020-01-02), [2020-01-02, 2020-01-03) t2 has 2 partitions: [2020-01-02, 2020-01-03), [2020-01-03, 2020-01-04) The following scenario is not allowed: t1 has 2 partitions: [2020-01-01, 2020-01-03), [2020-01-03, 2020-01-05) t2 has 2 partitions: [2020-01-01, 2020-01-02), [2020-01-02, 2020-01-03) However, if the materialized view uses monthly partition roll-up, the above scenario is allowed, because the materialized view only needs to generate one partition: [2020-01-01, 2020-02-01). --------- Co-authored-by: seawinde <daydayup005@yeah.net> Co-authored-by: seawinde <wusi@selectdb.com> # Conflicts: # fe/fe-core/src/main/java/org/apache/doris/mtmv/MTMVPartitionUtil.java # fe/fe-core/src/main/java/org/apache/doris/mtmv/MTMVRewriteUtil.java # fe/fe-core/src/main/java/org/apache/doris/nereids/rules/exploration/mv/MaterializedViewUtils.java # fe/fe-core/src/test/java/org/apache/doris/mtmv/MTMVRewriteUtilTest.java
