This commit adds the functionality of generate EFI_DEBUG_IMAGE_INFO
while loading the image.
This feature is described in UEFI Spec 2.10. Section 18.4.3.
The implementation ensures support for hardware-assisted debugging and
provides a standardized mechanism for debuggers to discover the load
address of an EFI application.

Hello Paul,
with

I got this output:

I found the PE-COFF headers of the EFI binaries in the provided locations:
(gdb) p *(char[0x44]*)0xbdbeb000
$1 = "MZ", '\000' <repeats 46 times>,
"RISCV\000\000\000RSC\005@\000\000\000PE\000"
(gdb) p *(char[0x84]*)0xbdd47000
$2 = "MZ", '\000' <repeats 58 times>, "\200", '\000' <repeats 67 times>,
"PE\000"
This looks good.
