lwip: allow setting LwIP tasks affinity via sdkconfig

Browse Source 
In some cases applications need to ensure that WiFi/BT related tasks
run on CPU1. This option can be used to set task affinity in such case.

Configure TCP/IP task stack size, used by LWIP to process multi-threaded TCP/IP operations.
Setting this stack too small will result in stack overflow crashes.

Allows setting LwIP tasks affinity, i.e. whether the task is pinned to
CPU0, pinned to CPU1, or allowed to run on any CPU.
Currently this applies to "TCP/IP" task and "Ping" task.
