This commit adds a new port "rp2" which targets the new Raspberry Pi RP2040 microcontroller. The build system uses pure cmake (with a small Makefile wrapper for convenience). The USB driver is TinyUSB, and there is a machine module with most of the standard classes implemented. Some examples are provided in the examples/rp2/ directory. Work done in collaboration with Graham Sanderson. Signed-off-by: Damien George <damien@micropython.org>
