  Load Pe32 Image protocol enables loading and unloading EFI images into memory and executing those images.
  This protocol uses File Device Path to get an EFI image.

/**

  Loads an EFI image into memory and returns a handle to the image with extended parameters.

  @param  This                The pointer to the LoadPe32Image protocol instance
  @param  ParentImageHandle   The caller's image handle.
  @param  FilePath            The specific file path from which the image is loaded.
  @param  SourceBuffer        If not NULL, a pointer to the memory location containing a copy of
                              the image to be loaded.
  @param  SourceSize          The size in bytes of SourceBuffer.
  @param  DstBuffer           The buffer to store the image.
  @param  NumberOfPages       For input, specifies the space size of the image by caller if not NULL.
                              For output, specifies the actual space size needed.
  @param  ImageHandle         The image handle for output.
  @param  EntryPoint          The image entry point for output.
  @param  Attribute           The bit mask of attributes to set for the load PE image.

  @retval EFI_SUCCESS           The image was loaded into memory.
  @retval EFI_NOT_FOUND         The FilePath was not found.
  @retval EFI_INVALID_PARAMETER One of the parameters has an invalid value.
  @retval EFI_UNSUPPORTED       The image type is not supported, or the device path cannot be
                                parsed to locate the proper protocol for loading the file.
  @retval EFI_OUT_OF_RESOURCES  The image was not loaded due to insufficient memory resources.
  @retval EFI_LOAD_ERROR        Image was not loaded because the image format was corrupt or not
                                understood.
  @retval EFI_DEVICE_ERROR      Image was not loaded because the device returned a read error.
  @retval EFI_ACCESS_DENIED     Image was not loaded because the platform policy prohibits the
                                image from being loaded. NULL is returned in *ImageHandle.
  @retval EFI_SECURITY_VIOLATION Image was loaded and an ImageHandle was created with a
                                valid EFI_LOADED_IMAGE_PROTOCOL. However, the current
                                platform policy specifies that the image should not be started.
