xzj7019 f7c106c709 [opt](nereids) enhance broadcast join cost calculation (#22092)
Enhance broadcast join cost calculation, by considering both the build side effort from building bigger hash table, and more probe side effort from bigger cost of ProbeWhenBuildSideOutput and ProbeWhenSearchHashTable, if parallel_fragment_exec_instance_num is more than 1.

Current solution gives a penalty factor on rightRowCount, and the factor is the total instance number to the power of 2.
Penalty on outputRows is not taken currently and will be refined in next generation cost model.

Also brings some update for shape checking:

update original control variable in shape file parallel_fragment_exec_instance_num to parallel_pipeline_task_num, if pipeline is enabled.
fix a be_number variable inactive issue.
