ESP32: Address -Wundef build errors and enable it for platform (#29728)

* [ESP32] Fix build errors when -Wundef compiler flag is enabled

* Enable -Wundef for ESP32

* Defining CHIP_SYSTEM_CONFIG_LWIP_PBUF_FROM_CUSTOM_POOL

Some platforms do not use the lwip from third_party/lwip and may not
have LWIP_PBUF_FROM_CUSTOM_POOLS defined in lwip/opt.h. When building
apps with -Wundef cflag enabled, it may fail to find LWIP_PBUF_FROM_CUSTOM_POOLS
hence this option. This defaults to LWIP_PBUF_FROM_CUSTOM_POOLS if
defined, otherwise 0.

* remove includes of <lwip/opt.h> and use <system/SystemConfig.h>
