From: Stefano Tondo <[email protected]>

Add SPDX_IMAGE_SUPPLIER and SPDX_SDK_SUPPLIER variables that allow
setting a supplier agent on image and SDK SBOM root elements using
the suppliedBy property.

These follow the existing SPDX_PACKAGE_SUPPLIER pattern and use the
standard agent variable system to define supplier information.
