URL: https://github.com/apache/doris/pull/49514
### What problem does this PR solve?
- Incorporate partition pruning into RBO rewrite rules after obtaining
available materialized view adjustments. This reduces partition version
comparison overhead for partitioned material化视图s, thereby improving performance.
- Set maximum time threshold for transparent query rewriting with default
value of 1000ms. Rewrite attempts will be terminated if exceeding this
threshold.
- Optimize code structure in transparent rewriting framework:
1. Replace Lambda expressions with conventional for-loops
2. Remove redundant member variables
- Cache available partitions of materialized views. Since calculating
available partitions for materialized views is time-consuming, caching can
significantly enhance performance.
