tcl/board: add pico-debug support
pico-debug is not a board; it is a virtual CMSIS-DAP adapter that
runs on the same RP2040 also being debugged. This is possible due
to pico-debug running on the normally-dormant second Cortex-M0+
core (Core1), providing debugging of the first core (Core0).
As such, it could be used on a variety of RP2040-based boards.
Since a flash driver is useful (if not essential), a flash driver
is included. This driver code originated on RPi's bespoke OpenOCD
fork; lipstick was added to this particular pig to make it more
presentable on OpenOCD proper.
