Accept USB BOOTSEL reboot on the UART firmware

Browse source 
The regular firmware now answers the EP0 vendor INFO and BOOTSEL reboot
requests with the AIO wire protocol, so switch-pico-config reboot bootsel
works when the Pico's USB side is on a PC. Wire constants move to
usb_management_protocol.h; other operations stall.
