test(tree): speed up createTableTree test setup

[brrichards]

Summary

Optimizes dense-table construction in the tableSchema benchmark test utility. Instead of inserting empty rows and then issuing one setCell op per cell, each row is now built with its cells pre-populated and the whole table is inserted with a single insertRows op.

Tested specifically against tableSchema memory benchmarks which run ~8 minutes faster.
