[OE-core][PATCH v11 2/4] spdx30: Add supplier support for image and SDK SBOMs

[stondo@gmail.com]

From: Stefano Tondo <stefano.tondo.ext@siemens.com>

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.
