Create "pico2-ice" target board (#5062)

Browse Source 
* Create "pico2-ice" target board

This board has an rp2350b chip on it, as well as a Lattice Semiconductor
iCE40UP5K FPGA. More details of this open hardware board here:

  https://pico2-ice.tinyvision.ai/

Tested on a pico2-ice board with:

  ~/go/bin/tinygo flash -target=pico2-ice src/examples/blinky1/blinky1.go

which blinks the GREEN LED (connected to GPIO0) on this board.

* More silkscreen labels for pico2-ice board

Reading the schematic and the rev2 board viewer:

https://raw.githubusercontent.com/tinyvision-ai-inc/pico2-ice/refs/heads/main/Board/Rev2/bom/ibom.html

concluded that the RP2350B GPIO pins are not labeled with these
pin numbers in the silkscreen. Instead, the silkscreen refers to
uses of the GPIOs or the ICE numbered pins. RP2340B devoted pins
map to the A1..4 B1..4 pins on the RP PMOD connector. Also
silkscreen "~0".."~6" are labeled as pins N0..N6.

* Added a smoketest for pico2-ice board and tidied up GPIO defs

Addresses review comments from aykevl.
