py: Add mp_raise_msg_varg helper and use it where appropriate.
...
This commit adds mp_raise_msg_varg(type, fmt, ...) as a helper for
nlr_raise(mp_obj_new_exception_msg_varg(type, fmt, ...)). It makes the
C-level API for raising exceptions more consistent, and reduces code size
on most ports:

stm32/{adc,machine_adc}: Change ADC clock and sampling time for F0 MCUs.
...
STM32F0 has PCLK=48MHz and maximum ADC clock is 14MHz so use PCLK/4=12MHz
to stay within spec of the ADC peripheral. In pyb.ADC set common sampling
time to approx 4uS for internal and external sources. In machine.ADC
reduce sample time to approx 1uS for external source, leave internal at
maximum sampling time.
