esp32/lwip: adjust some lwip options and update wifi lib

1. Modify TCP TX window from 2 to 4 to keep RX/TX window same size
２. Modify TCPIP task stack default size from 2048 to 2560 to avoid stack overflow
３. Update wifi lib for TCP performance optimization

Configure TCP/IP task stack size, used by LWIP to process multi-threaded TCP/IP operations.
The default is 2048 bytes, setting this stack too small will result in stack overflow crashes.
