Recent versions of the rp2040 sdk no longer contain the elf2uf2 tool. So, move that code to a new dedicated directory. This is in preparation for updating the rp2040 sdk version. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

Rewrite chipid.c so that it contains just the USB and canbus id manipulation code. Move the low-level chipid reading to bootrom.c. Also, introduce a new bootrom_reboot_usb_bootloader() function in bootrom.c so that the main.c code does not need to know the specifics of rebooting into the bootrom.

This adds the bootrom code needed to implement "reboot into bootloader" and "chipid" capabilities. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

This adds support for the new Raspberry Pi RP2350 micro-controllers. This has also been discussed at: https://klipper.discourse.group/t/support-for-rp2350-micro-controllers/19656
Note that the rp2350 has a serious hardware defect (RP2350-E9 errata) and as a result I do not recommend using this chip currently. See the link above for more details.
The code on this PR has a few known limitations (to be addressed in future PRs):
Only the first 30 GPIOs are supported. Support for the additional GPIOs on the rp2350b has not been added (nor support for ADC in general on the rp2350b).
-Kevin
EDIT: The chipid and reboot into bootloader functionality has also been implemented in this PR.
