chore: removed klona completely in setupUpdateTree (#40021)

## Description
We earlier had an issue where the oldUnEvalTree was getting mutated, it
happened because of some properties of updatedUnevalTree were getting
tied to evalTree in the getEvaluationOrder function. So any mutation on
evalTree which definitely will happen in the subsequent steps in the
evalAndValidateSubTree function would affect oldUnEvalTree. To prevent
this mutation we previously performed a deepClone which had a cost in
performance and this executed in evalTreeWithChanges and evalTree
further exacerbating performance.
To fix it we performed a deepClone on specific paths of
updatedUnevalTree to evalTree thereby when make an assignment of
updatedUnevalTree to oldUnvalTree these deepClones isolate mutations.
This has led to a 0.3 seconds reduction in LCP and reduces the overall webworker
scripting by 9-10%.

## Summary by CodeRabbit

- **Tests**
- Updated evaluation test assertions to focus on performance
expectations rather than strict operation counts.
- **New Features**
- Introduced a method to directly set historical evaluation data,
improving clarity and functionality in the evaluation workflow.
- Renamed and modified the evaluation order method to enhance clarity
regarding its functionality.
