drivers: ethernet: Modify RX thread creation and update KConfig 



This change will allow users to configure the Ethernet RX thread
according to their specific real-time requirements.
Adding preemptive threading helps to reduce jitter and
the impact of Ethernet traffic on real-time performance.

	  RX thread priority

	  This option allows to configure the priority of the RX thread that

	  handles incoming Ethernet packets.

	  Switching between preemptive and cooperative scheduling can be done by

	  NET_TC_THREAD_PREEMPTIVE.

	  Preemptive scheduling can lead to more responsive handling of network traffic,

	  especially under high load.
