mcu-lvgl-4848s040: add Guition ESP32-S3-4848S040 initial config

- mipi_rgb GUITION-4848S040 model, ST7701S init over SPI (48/47)
- GT911 touch mirrored like the image, backlight on GPIO38
- clock and status pages (status until Home Assistant connects),
  same navigation bar as the other LVGL displays
- IPv6-only network
