soc: nrf53: Port nrf53_cpunet_mgmt_init to soc_early_init_hook

/**
* @brief Initialize the CPU network management system for the nRF5340.
*
* This function sets up an on-off manager for managing the network core of the nRF5340.
* It configures the necessary transitions for starting and stopping the network core.
*
* The function also ensures proper handling of GPIO pin forwarding when the
* `CONFIG_SOC_NRF_GPIO_FORWARDER_FOR_NRF5340` configuration is enabled. Pins are
* forwarded to the network core during startup and reassigned to the application
* core during shutdown.
*
* @return 0 on success, or a negative error code on failure.
*
* @note This function relies on the `onoff_manager` API to manage the start and stop
* transitions for the network core.
