GH-816: Presize JsonStringArrayList vector results

[schlosna]

What's Changed

Presize JsonStringArrayLists when constructing them as part of ValueVector#getObject conversions.

FixedSizeListVector#getObject already performs this optimization; however, ListVector, ListViewVector, LargeListVector, and LargeListViewVector do not yet presize the result JsonStringArrayList requiring dynamic reallocations as elements are converted & added. This can become a scalability bottleneck when using these types.

Closes #816.

Looks like the formatter isn't happy:

There's more formatting errors than just that. Can you mvn spotless:apply?

Thanks for the quick review. Apologies about the format issue, I had tried to fix up while mobile. I've run mvn spotless:apply & pushed.
