Defines the revision of the EFI_LOADED_IMAGE_PROTOCOL structure.
All future revisions will be backward compatible to the current revision.

Parent image's image handle. NULL if the image is loaded directly from
the firmware's boot manager.
@param SystemTable
The image's EFI system table pointer.
@param DeviceHandle
The device handle that the EFI Image was loaded from.
@param FilePath
A pointer to the file path portion specific to DeviceHandle
that the EFI Image was loaded from.
@param Reserved
Reserved. DO NOT USE.
@param LoadOptionsSize
The size in bytes of LoadOptions.
@param LoadOptions
A pointer to the image's binary load options.
@param ImageBase
The base address at which the image was loaded.
@param ImageSize
The size in bytes of the loaded image.
