rp2/machine_pin: Add support for named pins and alternate functions. This commit adds support for generating named pin mappings for all pins including CPU, board-defined, LED and externally controlled pins. CPU pins are mapped to `pin_GPIO<n>`, externally-controlled pins are mapped to `pin_EXT_GPIO<n>`, and defined conditionally (up to 10 pins, and can be expanded in the future), and they are non-const to allow `machine-pin.c` to write the pin object fields. Both CPU and externally controlled pins are generated even if there's no board CSV file; if one exists it will just be added to board pins.
