Now that the ISR callback mechanism (from #14382) costs essentially zero — just a function pointer registration, no task or queue — enable wake-on-RX by default for all ESP32 UART instances. This reduces RX buffer overflow risk by waking the main loop immediately when data arrives instead of waiting for the ~16ms select timeout. Remove the opt-in request_wake_loop_on_rx() API since all ESP32 UART instances now get this automatically.
