…tests Avoid immediately-invoked lambda coroutines with captures in AsyncQueueTest and SemaphoreTest to prevent stack-use-after-scope under ASan. Pass Semaphore by reference to coroutine task in DestructionWhileProcessWaitersScheduled so the test retains sole ownership of the Semaphore shared_ptr.

Commit Message:
Add a
Coroutine::AsyncQueueimplementation. This is a useful utility to pass buffer / items among coroutines. Immediate use case is in APM's AI filter manager implementation that's forthcoming in a next PR.AsyncQueue::pushandAsyncQueue::popcan be used withco_await. Non-blocking methods are available.The implementation can share capacity among multiple instances. It's typical for a buffer to be passed in a chain of queues, and we'd like the total bytes in the queues to be bound in size.
I used AI to generate this PR. I have read the code and understand it.
