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.
