Let broker-backed eventfd reads and writes honor the file description O_NONBLOCK state instead of forcing nonblocking operations. Use the existing event counter pollee wakeups from add/consume control responses for local waiters. Add broker integration coverage for clearing O_NONBLOCK, blocking read and write wakeups, and poll/epoll readiness updates. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Enables broker-backed eventfds to honor the file description's O_NONBLOCK state instead of forcing broker operations to be nonblocking. The local event counter already wakes waiters from add/consume control-response readiness, so blocking read/write and poll/epoll readiness now work over the broker-backed path. Adds broker integration coverage for clearing O_NONBLOCK, blocking read/write wakeups, and poll/epoll readiness updates.
