event: Extract event_poll loops to `event_poll_until` macro

A pattern that is becoming common across the project is to poll for events until
a certain condition is true, optionally passing a timeout. To address this
scenario, the event_poll_until macro was created and the job/channel/input
modules were refactored to use it on their blocking functions.
