stm32/pyb_can: Add ability to calculate CAN bit timing from baudrate.
...
Calculate the bit timing from baudrate if provided, allowing sample point
override. This makes it a lot easier to make CAN work between different
MCUs with different clocks, prescalers etc.
Tested on F4, F7 and H7 Y/V variants.

all: Format code to add space after C++-style comment start.
...
Note: the uncrustify configuration is explicitly set to 'add' instead of
'force' in order not to alter the comments which use extra spaces after //
as a means of indenting text for clarity.

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: Add support for FDCAN peripheral, exposed as pyb.CAN.
...
The new fdcan.c file provides the low-level C interface to the FDCAN
peripheral, and pyb_can.c is updated to support both traditional CAN and
FDCAN, depending on the MCU being compiled for.
