Replace occurrences of AsyncSemaphore with JTF-aware semaphore #9424
Description
After updating our analyzer packages, using AsyncSemaphore is now banned. I tried to replicate the same behavior with an allowed type, but was running into test failures so assigning to @drewnoakes because I do not know this code very well.
In the meantime, I'm adding a suppression to our FUTDC usages of this type.
