Change the LockCreated event to ContentionLockCreated (#86817)

- The event was added in .NET 8, I have updated the event name based on the suggestion in https://github.com/microsoft/perfview/pull/1731#issuecomment-1293961643.
- The name now matches the convention used for most other events, and shows up as Contention/LockCreated as expected in PerfView
