Share tree display traversal and rendering

[joseph-isaacs]

Summary

• add shared tree traversal and indented/branch renderers in vortex-utils
• migrate array and expression tree displays to the shared implementation
• preserve existing display output while removing duplicated traversal code

Footnotes

1. 51 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on develop (66c447e) during the generation of this report, so adab5b8 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
