Jeff Epler 6e153d9948 raspberrypi: implement reset, reset_to_bootloader 
This makes all the following work:
 * normal microcontroller.reset()
 * reset into safe mode or UF2 bootloader via microcontroller.on_next_reset()
 * reset into UF2 bootloader via the "1200 baud trick"

The implementation of reset_cpu is from micropython.

Add initial RP2040 support 
The RP2040 is new microcontroller from Raspberry Pi that features
two Cortex M0s and eight PIO state machines that are good for
crunching lots of data. It has 264k RAM and a built in UF2
bootloader too.
