1 event loop per thread. Instead of 3.

uWebSockets and uSockets will need to be upgraded to match the changes.

Previously:
- Bun had a separate kqueue/eventfd just for async wakeups.
- Bun had a separate kqueue/epoll just for reading files non-blocking in the same thread

This commit unifies it into one event loop per thread
