Motivation: Systems depending on Netty may benefit (telemetry, alternative even loop scheduling algorithms) from knowing the number of channels assigned to each EventLoop. Modification: Expose the number of channels registered in the EventLoop via SingleThreadEventLoop.registeredChannels. Result: Fixes #8276.
