loader: lsefi: Print more information

[manu]

Summary

Printing the EFI_HANDLE pointer isn't very useful.
If the handle have a IMAGE_DEVICE_PATH or a DEVICE_PATH protocol print it.
This makes it easier to see which devices are present and what protocol they
expose.

Tested on u-boot based and edk2 based firmware

It's better than what we have as is... Question about whether or not we have multiple paths that would be useful or not (I can't recall that deatil). If so, please adjust to print both (I still approve), if not just indicate in comments (and I also still approve)

Can you have both an image path and a devpath for the handle? And would you want to print them both?

You can't if I understand correctly the UEFI driver model.
