Sylvio Alves a6756c36e9 samples: wifi: esp32s2_saola: reduce RAM usage This modification frees up around ~10kB of RAM and make sample code working again. 1) Reduced net packet size and count. 2) Increase Wi-Fi heap to avoid memory allocation failure. 3) Keep log as minimal.

Wi-Fi sample
############

Overview
********

This sample allows testing Wi-Fi drivers for various boards by
enabling the Wi-Fi shell module that provides a set of commands:
scan, connect, and disconnect.  It also enables the net_shell module
to verify net_if settings.

Building and Running
********************

Verify the board and chip you are targeting provide Wi-Fi support.

For instance you can use TI's CC3220 by selecting the cc3220sf_launchxl board.
