stm32/modstm: Add MICROPY_PY_STM_CONST flag, clear it for STM32WL5.
MICROPY_PY_STM_CONST defaults to 1 if MICROPY_PY_STM is set. Overriding to 0 disables the named register peripheral constants being including in the stm32 module. This saves about 7.5KB of code size for the STM32WL55, which is significant as this SoC doesn't have a lot of flash. Signed-off-by: Angus Gratton <angus@redyak.com.au>
