Avoid the cost of primordial push calls for each formatted entry by using indexed writes to collect formatted Set and Map entries. Similar approach as for this PR: #66872

In local 30-sample benchmarks, inspecting 50-element collections improved
throughput by 15.9% for Sets and 8.7% for Maps. Reverse comparisons
confirmed both gains, with no corrected-significant regressions in the
broader comparison.
