stm32/adc: make resolution flag checks consistent for all STM32 families

[crasbe]

Description

As discovered in https://github.com/RIOT-OS/RIOT/pull/20773#discussion_r1665435304, some variants of the STM32 ADC peripheral use magic numbers in an undocumented way to check if the ADC resolution has a valid value or or not: https://github.com/RIOT-OS/RIOT/blob/master/cpu/stm32/periph/adc_f0_g0_c0.c#L103-L106 https://github.com/RIOT-OS/RIOT/blob/master/cpu/stm32/periph/adc_f2.c#L112-L114 https://github.com/RIOT-OS/RIOT/blob/master/cpu/stm32/periph/adc_f3.c#L196-L199 https://github.com/RIOT-OS/RIOT/blob/master/cpu/stm32/periph/adc_f4_f7.c#L131-L134 https://github.com/RIOT-OS/RIOT/blob/master/cpu/stm32/periph/adc_l4_wb.c#L220-L223 https://github.com/RIOT-OS/RIOT/blob/master/cpu/stm32/periph/adc_wl.c#L121-L124

Some other implementations explicitly check if the resolution value is one of the valid values, so IMO this is the better approach: https://github.com/RIOT-OS/RIOT/blob/master/cpu/stm32/periph/adc_f1.c#L146-L149 https://github.com/RIOT-OS/RIOT/blob/master/cpu/stm32/periph/adc_l0.c#L120-L126 https://github.com/RIOT-OS/RIOT/blob/master/cpu/stm32/periph/adc_l1.c#L149-L155

I have the following STM32 boards available: NUCLEO-F413ZH NUCLEO-G474RE (not supported yet, seems to have the same ADC as the H7 series and quite similar to L4, just a little more options) NUCLEO-L073RZ (irrelevant, won't be changed) NUCLEO-L452RE P-NUCLEO-WB55 (duplicate for L4)

So we're still missing F0/F0/C0, F2, F3 and WL boards for testing. Maybe I can get some of them from Mouser in the future, but maybe someone else has some of these boards for testing.

I have access to F207 and F334. I will try to arrange access to C031.
