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
