[Feat][Spark] Memory tuning for GraphAr Spark

[acezen]

Is your feature request related to a problem? Please describe.
Currently, GraphAr spark implementation can not handle very large dataset efficiency and got OOM error. We need to tuning the memory usage of GraphAr spark and make it scalable.

Describe the solution you'd like

• serialize RDD object with persist [Feat][Spark] Memory tuning for GraphAr spark with persist and storage level #326
• tuning GC (especially when vertex chunk size is very small that would generate a large amount of rdd object)
• tuning data structure
