py/objlist,stm32,esp32: Add helpers for creating/ensuring list args.
...
Simplifies the pattern of an optional arg which can be a list of at
least a certain length, otherwise one is lazily initialised.
Modify pyb.CAN and ESP-NOW APIs to use the helper. Note this changes
the return type of pyb.CAN.recv() from tuple to list.

stm32/pyb_can: Make pyb.CAN baud calculation a little more forgiving.
...
Not every baudrate or sample point combination has an exact match,
but getting within 1% on sample point and .1% on baud rate should
always be good enough.
Because the search goes from shorter bit periods (lowest brp) and
increases, the first match which meets this criteria should still mostly be
the best available.

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.
