bp #45148

### What problem does this PR solve?
Problem Summary:
Optimize reading of maxcompute partition tables:
1. Introduce batch mode to generate splits for Maxcompute partition
tables to optimize scenarios with a large number of partitions. Control
it through the variable `num_partitions_in_batch_mode`.
2. Introduce catalog parameter `mc.split_cross_partition`. The parameter
is true, which is more friendly to reading partition tables, and false,
which is more friendly to debug.
3. Add `-Darrow.enable_null_check_for_get=false` to be jvm to improve
the efficiency of mc arrow data conversion.
