02620c2236 stm32/subghz: Add STM32WL55 subghz radio interface to stm module. 
This is the minimum C interface to allow a modem driver to be built in
Python.  Interface is simple, with the intention that the micropython-lib
driver is the main (only) consumer of it.

2c62adb42c stm32/powerctrlboot: Support STM32WL system clock from HSE+PLL. 
Switches default on the NUCLEO_WL55 board to use the HSE oscillator powered
from PB0_VDDTCXO pin.

Build-time configuration can select from MSI internal oscillator (previous
default), HSE via crystal, or HSE bypass with TCXO powered from PB0_VDDTCXO
pin (new default)
