Switch time profiling to use lazy load stop and collect method by default

[IlyasShabi]

What does this PR do?:
Switch time profiling to use stopAndCollect instead of the legacy stop, and remove the old code path.

Motivation:
PR #287 showed (via CI benchmarks) that stopAndCollect cuts memory usage by ~52% for a significant profile size. This change makes using stop and collect as the default for time profiling.
