wangjianyu3 cab92d310d boards/rp2040: add USB fastboot composite support for waveshare boards 
Add a CDC/ACM (console) + USB fastboot (ADB "fastboot" personality)
composite device to the shared rp2040_composite.c board glue, and a
new "fastboot_usb" defconfig for waveshare-rp2040-zero and
waveshare-rp2040-lcd-1.28.

- boards/arm/rp2040/common/src/rp2040_composite.c: add a third
  composite slot for CONFIG_USBADB (covers both plain ADB and, with
  CONFIG_USBFASTBOOT, the "fastboot" personality of the same driver)
  alongside the existing MSC/CDC-ACM slots.  While adding this,
  fixed a latent bug: the CDC/ACM block never advanced ifnobase/
  strbase after filling in its own slot, because CDC/ACM used to
  always be the *last* device in the composite (nothing downstream
  ever needed the incremented values).  Now that a device can follow
  CDC/ACM, the missing increment caused the fastboot interface to be
  assigned the same USB interface number as CDC/ACM's control
  interface (both 0), which the Linux kernel rejects with "Duplicate
  descriptor for config 1 interface 0 altsetting 0, skipping" and
  drops the fastboot interface entirely (confirmed via lsusb -v and
  disassembly of the generated board_composite_connect() code).

- boards/arm/rp2040/waveshare-rp2040-zero/configs/fastboot_usb and
  boards/arm/rp2040/waveshare-rp2040-lcd-1.28/configs/fastboot_usb:
  new defconfig booting directly into fastbootd
  (CONFIG_INIT_ENTRYPOINT="fastbootd_main", no nsh) which brings up
  the CDC/ACM + fastboot composite via
  CONFIG_SYSTEM_FASTBOOTD_USB_BOARDCTL as soon as fastbootd starts,
  so the CDC/ACM sub-interface still provides a console for boot/
  fastbootd log visibility without requiring a wired UART, while the
  fastboot vendor interface is what `fastboot devices`/`getvar` talk
  to.
