Fix nested value iteration

[andyfengHKU]

This PR fixes the performance issue of iterating nested data types. Now we avoid creating children value objects at iteration time (LIST still have to create since the size cannot be known before iteration, but we make sure it never resize to smaller size so the performance issue should be amortized.)

Meanwhile I always remove used APIs related to nodeVal and relVal. And remove all APIs that are triggering copy constructor from Value class.

TODOs

• propagate change to on Rust side
• propagate change to C, Java and NodeJS
