spdx30_tasks: Add support for exporting PACKAGECONFIG to SPDX

Introduce the SPDX_INCLUDE_PACKAGECONFIG variable, which when enabled causes
PACKAGECONFIG features to be recorded in the SPDX document as build parameters.

Each feature is recorded as a DictionaryEntry with key PACKAGECONFIG:<feature>
and value enabled or disabled, depending on whether the feature is active in
the current build.

This makes the build-time configuration more transparent in SPDX output and
improves reproducibility tracking.

This makes the build-time configuration more transparent in SPDX output and
improves reproducibility tracking. In particular, it allows consumers of the
SBOM to identify enabled/disabled features that may affect security posture
or feature set.
