Integrate STM32 battery monitoring into AnalogBatteryLevel, supporting
external GPIO ADC pins as well as internal VBAT channel.
Features:
- ADC reading using STM32 LL (Lower Layer) macros supporting external
ADC channels and internal VBAT channel (AVBAT)
- ADC compensation using STM32 LL macros with factory-calibrated VREFINT
(AVREF) for accurate voltage measurement
- LFP battery OCV curve for STM32WL using AVBAT (STM32 VDD absolute
maximum supply voltage 3.9V, direct connection of Li-Po batteries is
not supported)
Internal VBAT channel implemented in:
- Russell
- RAK3172
In these variants, ADC_MULTIPLIER = (1.01f * 3) = 3.30 as there is a
3:1 internal divider (DS13105 Rev 12 §5.3.21), and a bit of tolerance
as the actual 10% spec leads to readings much too high.

Also move RAK3172 and new EBYTE_E77_MBL define to variant.h, as this makes VSCode know about the defines properly...

* Show ExternalNotification as excluded if it is
* Enable ExternalNotification, SerialModule and RangeTest on STM32WL
* Misc fixes for #7797 - ARCH_STM32 -> ARCH_STM32WL, use less flash by dropping weather station support for serialmodule, set tx/rx pins before begin
* Enable Serial1 on RAK3172, make SerialModule use it (console is on LPUART1)
* Fix SerialModule on RAK3172, fix board definition of RAK3172 to include the right pin mapping.
