Tree: Switch to async generators

Async generation helps remove many roadblocks to managing tasks
using threads. It should allow for abortables and modern-day paradigms.

NOTE: Exllamav2 itself is not an asynchronous library. It's just
been added into tabby's async nature to allow for a fast and concurrent
API server. It's still being debated to run stream_ex in a separate
thread or manually manage it using asyncio.sleep(0)
