extmod/network_ninaw10: Switch to using soft-timer for polling.
This patch simplifies the connection and sockets polling code, by switching to a soft-timer to schedule polling code, and by using one node for scheduling. This also fixes any issues that could result from using a heap allocated machine_timer, and includes better handling of the sockets poll list. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
