Implement WaitPoll for Fuchsia

Fuchsia's libc provides `select` and `poll` but not `epoll`.

This CL adds a `WaitPoll` method, which is modeled after `WaitSelect` but uses `poll`. The pre-existing `WaitPoll` method was renamed to `WaitPollOneDispatcher`.

TESTED="2p video call on Fuchsia. WaitPoll is faster compared to
WaitSelect, primarily because WaitSelect pessimistically calls
getsockopt(SO_ERROR) on each fd, while WaitPoll does so only on fds that
have entered an error state."
