[PATCH v3 07/11] spdx30: Include recipe base PURL in package external identifiers

[Stefano Tondo <stondo@gmail.com>]

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

Include the recipe's base PURL (from oe.purl.get_base_purl) in the
external identifiers for built packages alongside any PURLs from
SPDX_PACKAGE_URLS.

This ensures that every built package has a pkg:yocto PURL (e.g.,
pkg:yocto/core/zlib@1.3.1) in its external identifiers, improving
tool interoperability and supply chain tracking.
