fix(examples): declare Adafruit BusIO in ESP32 GFX-based examples 

The ESP-IDF compile path stages exactly the libraries declared in the
example (no transitive resolution), so Adafruit_GFX.h failing to find
Adafruit_I2CDevice.h broke esp32s3-ili9341-hello and esp32-oled-4pin-i2c
with 'Compilation produced no firmware'. The other ESP32 GFX examples
(esp32-oled, esp32-bmp280) already declare BusIO explicitly.
