randy 329830e553 mcu-m5paper: rework on M5Stack components, battery mode with forecast ...

Rewrite of the old config on the core ESPHome components (it8951, gt911,
bm8563, sht3xd):
- USB: always on, forecast screen redrawn every 15 min, forecast
  refreshed every hour and when Home Assistant connects
- battery: BM8563 timer wakes the board every 15 min (off 1:00-5:00),
  it draws the stored forecast and cuts power; WiFi only when the
  forecast is older than 6 h
- mode detected by trying to power off; battery voltage drop on USB
  triggers the battery cycle
- hourly forecast via weather.get_forecasts, 48 h kept in the FM24C02
  EEPROM (include/m5paper_weather.h)
- OTA image confirmed before power-off, battery wake-ups are shorter
  than boot_is_good_after
- status screen with "Made for ESPHome" logo, IPv6 addresses first
