Slow scheduling performance when combining dependencies
Reproduction steps:
1. Open the user's attached project "EmptyTestBed.zip"
2. Enter Play mode
3. Open the Profiler window and select a frame
4. Observe "N Parallel Jobs With Paired Dependencies", "N Parallel Jobs" and "N Linear Jobs" usage in the Profiler Hierarchy and Timeline
Expected result: "N Parallel Jobs With Paired Dependencies" costs somewhat more of the CPU and time than "N Parallel Jobs" and "N Linear Jobs"
Actual result: "N Parallel Jobs With Paired Dependencies" costs a lot more of the CPU and time than "N Parallel Jobs" and "N Linear Jobs"
Reproducible with: 2019.4.36f1, 2020.3.31f1, 2021.2.15f1, 2022.1.0b11, 2022.2.0a8
Note: CombineDependencies calling ScheduleBatchedJobs might be the source of this issue
