flash_usb: Use hexid "2e8a:0003" for rp2040 already in bootloader mode 

Use a USB hex id to indicate that the device is already in bootloader
mode.  This makes the rp2040 flashing code similar to the other
boards.

## Changes
20220616: It was previously possible to flash an rp2040 in bootloader
mode by running `make flash FLASH_DEVICE=first`. The equivalent
command is now `make flash FLASH_DEVICE=2e8a:0003`.
20220612: The rp2040 micro-controller now has a workaround for the
"rp2040-e5" USB errata. This should make initial USB connections more
reliable. However, it may result in a change in behavior for the

If the device is already in bootloader mode, use 'first' as FLASH_DEVICE.
This will use rp2040_flash to flash the first available rp2040.
If the device is already in bootloader mode it can be flashed with the
following command:
make flash FLASH_DEVICE=2e8a:0003
Alternatively, one can flash rp2040 boards like the Pico by manually
entering bootloader mode(hold bootsel button during powerup), mount the
device as a usb drive, and copy klipper.uf2 to the device.
