Add http_request support to LibreTiny platform

**Describe the problem you have/What new integration you would like**

Add http_request support to LibreTiny platform, in the same way as esp8266

**Please describe your use case for this integration and alternatives you've tried:**

Make any http request with a LibreTiny device

**Additional context**

Since LibreTiny support was added to ESPHome on 2023.9, I would like to use the http_request component on a LibreTiny device.
The HTTPClient library is implemented on LibreTiny : https://docs.libretiny.eu/ltapi/class_h_t_t_p_client/
Since the arduino esp32 implementation of http_request uses the Arduino HTTPClient library too, is it as simple as adding the LibreTiny platform to init.py ?

Start by comparing the existing ESP8266 and Arduino ESP32 http_request implementations, then inspect the platform registration in init.py. Check the LibreTiny HTTPClient documentation linked in the issue and verify that the component builds for LibreTiny and can make an HTTP request on a supported device.
