Reduce priority of Windows thread pool work items (#44121)

John Tur created 1 month ago

`WorkItemPriority::High` will enqueue the work items to threads with
higher-than-normal priority. If the work items are very intensive, this
can cause the system to become unresponsive. It's not clear what this
gets us, so let's avoid the responsiveness issue by deleting this.

Release Notes:

- N/A
