spdx3: support to override the version of a package in SBOM 3

By default, still use ${PV} as the the version of a package in SBOM 3
$ bitbake acl
$ jq . tmp/deploy/spdx/3.0.1/core2-64/packages/package-acl.spdx.json
...
    {
      "type": "software_Package",
       ...
      "name": "acl",
      "software_packageVersion": "2.3.2"
    },
...

Support to override it by setting SPDX_PACKAGE_VERSION, such as
set SPDX_PACKAGE_VERSION = "${EXTENDPKGV}" in local.conf to append
PR to software_packageVersion in SBOM 3
$ echo 'SPDX_PACKAGE_VERSION = "${EXTENDPKGV}"' >> conf/local.conf
$ bitbake acl
$ jq . tmp/deploy/spdx/3.0.1/core2-64/packages/package-acl.spdx.json
...
    {
      "type": "software_Package",
       ...
      "name": "acl",
      "software_packageVersion": "2.3.2-r0"
    },
...
