Jonathan Bell 592b8da71a probe: add CMSIS-DAP PIO-driven implementation

CMSIS-DAP implementations explicitly use CPU bitbash to control SWD and
SWDIO, but we can do better. Transfers are handed off to PIO in phases,
which gets us deterministic clock timing as well as freeing the CPU up
for other tasks.

Picoprobe

Picoprobe allows a Pico / RP2040 to be used as USB -> SWD and UART bridge. This means it can be used as a debugger and serial console for another Pico.

Documentation

Picoprobe documentation can be found in the Pico Getting Started Guide. See "Appendix A: Using Picoprobe".
