extmod/machine_i2c: Call MICROPY_PY_EVENT_HOOK during i2c.scan().

robert-hh · dpgeorge · commit 0b26efe73dd3 · 2022-08-31T12:06:11.000+10:00
Avoiding a watchdog reset during i2c.scan() if the hardware is not properly set up (eg on esp8266), and also allowing to stop the scan with a KeyboardInterrupt. Fixes issue micropython#8876.
