  [rtsan] Add I/O multiplexing interceptors (#115227)

Intercepts in the family of `poll`, `select` and modern equivalents
`epoll` (linux only) and `kqueue` bsd family only.

These calls mirror the names of the system calls they call, which have
been verified on mac at least (e.g. kevent calls the system call
kevent).
