Watchdog timer support?

@earlephilhower The Pico SDK provides hardware_watchdog support. Is this avaliable in Arduino Pico? Would be useful for Raspberry Pico W projects for hardware reset/reboot.

If not, I'd be OK with adding it. I have familiarity with the Pico SDK but not arduino-pico core, if you can point me in the right direction in the core?

I have not added it, but you can access the raw SDK functions just by including the proper headers.

If you're volunteering :smile: , then an addition to the RP2040 class or a new Watchdog object could be added to the core.

@earlephilhower I am volunteering, we (adafruit) need this functionality.
