This change is intended for the meta layer.

It enhances support for systemd-boot when used with a Unified 
Kernel Image (UKI), which includes the kernel and initramfs. 
This change is driven by our requirement to handle firmware 
artifacts (specifically DTBs) independently of the HLOS.

We generate a separate FIT image containing only DTBs, which is 
then packed as a VFAT image (dtb.bin) and used during boot. This 
aligns with a multi-DTB setup, where the appropriate DTB is 
selected dynamically at boot time based on the platform.
