Support multi-I2C and fix ESP32-S3 USB logging

Add dynamic I2C bus selection for battery gauge to support boards with multiple I2C controllers (e.g., Sticky uses Wire1 to avoid conflicts with GT911 touch). Fix logging on ESP32-S3 USB-Serial-JTAG by using esp_rom_printf instead of Serial, which incorrectly reports disconnected state.
