efi_loader: add dbginfodump.efi
Provide a test application to dump the EFI_DEBUG_IMAGE_INFO_TABLE
as implemented in EDK II.
EFI_DEBUG_IMAGE_INFO is not packed in contrast to many other EFI
structures.
As of today EDK II when removing an entry in the EfiDebugImageInfoTable
just sets NormalImage = NULL but does not compact the array. So
TableSize reflects the number of non-NULL entries and not the array
size as reported independently in
https://github.com/tianocore/edk2/pull/11013 and
https://github.com/tianocore/edk2/pull/11019.
The current implementation tolerates this deviation from the UEFI
specification.
This is what the output may look like:
