J. Nick Koston 482721d1ce [libretiny] Tune oversized lwIP defaults for ESPHome ...

The Beken/RTL SDKs ship lwIP defaults tuned for a general-purpose WiFi
SoC: TCP_SND_BUF=10*MSS (14.6KB), MEM_SIZE=32KB, 12 TCP + 22 UDP
sockets. These waste significant RAM on memory-constrained chips.
ESPAsyncWebServer allocates malloc(tcp_sndbuf()) per response chunk,
and at 14.6KB this causes OOM on BK7231N.

This tunes lwIP to match ESP32/ESP8266 ranges:
- TCP_SND_BUF/TCP_WND: 4*MSS (was 10*MSS)
- MEM_SIZE: 12KB BK72XX / 16KB RTL,LN (was 32KB)
- Socket counts: dynamic from component registrations
- All derived pool sizes adjusted accordingly

Also splits socket consumer tracking into TCP/UDP, adds
get_socket_counts() API, and updates ESP32 to use it.
