xen, rpi4: add xen-rpi-u-boot-scr recipe for default u-boot script

Add a new xen-rpi-u-boot-scr recipe to PROVIDE u-boot-default-script
instead of using a bbappend to rpi-u-boot-scr.

This allows the new recipe to be selected by indicating it as
PREFERRED_PROVIDER of u-boot-default-script, and then do that in the
Xen on Raspberry Pi 4 config file, xen-raspberrypi4-64.inc.
