feat(cli): support app-private esp-idf components + bump ESP32 platform

[yingtao450]

cli_build.py: when building for ESP32, expose <app_root>/esp_components to the platform build via the TUYAOS_EXTRA_COMPONENT_DIRS env var (consumed by platform/ESP32/tuya_open_sdk/CMakeLists.txt, which appends each root to EXTRA_COMPONENT_DIRS so every subdir becomes an esp-idf component). This is convention-over-configuration: an app just drops components under esp_components/ with no Kconfig or config key. Merges with any pre-exported value rather than overwriting, so CI/callers can add extra roots. Gated on the ESP32 platform.

platform_config.yaml: bump ESP32 pin to 012b6009 (TuyaOpen-esp32 master), which carries the matching TUYAOS_EXTRA_COMPONENT_DIRS consumer and the adapter include-dir glob.
