J. Nick Koston 3f74726f00 [core] Extend fast select optimization to LibreTiny platforms
Extend the ESP32 lwip_select() replacement (direct rcvevent reads +
FreeRTOS task notifications) to all LibreTiny platforms (bk72xx,
rtl87xx, ln882h).

All LibreTiny platforms have LwIP >= 2.1.3 with
lwip_socket_dbg_get_socket() and FreeRTOS task notifications. The
thread safety argument is actually stronger on LibreTiny since all
platforms are single-core ARM Cortex-M, eliminating cross-core
memory ordering concerns entirely.

Introduces USE_LWIP_FAST_SELECT feature define (set from Python
codegen for ESP32 and LibreTiny) replacing per-platform USE_ESP32
guards. The only platform-specific difference is FreeRTOS header
paths (freertos/FreeRTOS.h on ESP-IDF vs FreeRTOS.h on LibreTiny).

Expected impact on LibreTiny (same as ESP32):
- ~17x faster socket polling (direct rcvevent vs lwip_select)
- ~3.5 KB flash savings (dead code elimination of lwip_select)
- ~56 bytes static RAM savings (fd_set members excluded)
- ~200-300 bytes heap savings (UDP wake socket eliminated)

Tests for ESPHome

This directory contains some tests for ESPHome. At the moment, all the tests only work by simply executing esphome over some YAML files that are made to test whether the yaml gets converted to the proper C++ code.

Of course this is all just very high-level and things like unit tests would be much better. So if you have time and know how to set up a unit testing framework for python, please do give it a try.

When adding entries in test_.yaml files we usually need only one file updated, unless conflicting code is generated for different configurations, e.g. wifi and ethernet cannot be tested on the same device.

Current test_.yaml file contents.

test6.yaml RP2040 wifi N/A
test7.yaml ESP32-C3 wifi N/A
