spdx30: Provide software_packageUrl field in SPDX 3.0 SBOM

Define var-SPDX_PACKAGE_URL to provide software_packageUrl field [1][2]
in SPDX 3.0 SBOM, support to override with package name
SPDX_PACKAGE_URL:<pkgname>

Currently, the format of purl is not defined in Yocto, set empty for now
until we have a comprehensive plan for what Yocto purls look like.
But users could customize their own purl by setting var-SPDX_PACKAGE_URL
