Documentation/rp2040: document fastboot_usb config for waveshare boards

Add a "fastboot_usb" section to the waveshare-rp2040-zero and
waveshare-rp2040-lcd-1.28 board doc pages, describing the USB fastboot
composite configuration added by the previous commits: fastbootd runs
on boot instead of NSH, composed together with CDC/ACM for the
console, and reachable on the host via fastboot devices/getvar/reboot.
