Carson Wang d1a1376029 [SPARK-28356][SQL] Do not reduce the number of partitions for repartition in adaptive execution
## What changes were proposed in this pull request?
Adaptive execution reduces the number of post-shuffle partitions at runtime, even for shuffles caused by repartition. However, the user likely wants to get the desired number of partition when he calls repartition even in adaptive execution. This PR adds an internal config to control this and by default adaptive execution will not change the number of post-shuffle partition for repartition.

## How was this patch tested?
New tests added.

Closes #25121 from carsonwang/AE_repartition.
