iabdalkader c214c9e648 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.
