Increase timeout in tests and review redundant JSON changes

Updated `incrementTestDoneSignal.Wait` timeout from 5s to 10s in
`UsingInterlockedOps.cs` to ensure tests have sufficient time to
complete. Reviewed `xunit.runner.json` for redundant changes to
`parallelizeTestCollections` property, which remains set to `true`.
