[PATCH v16 0/5] spdx30: PURL and source download enrichment

[Stefano Tondo <stondo@gmail.com>]

This series enhances Yocto's SPDX 3.0 output with ecosystem-specific
Package URLs, Git source version tracking, and configurable SBOM
generation improvements.

Changes since v14 (addressing Joshua's review of v14 patches 3/4 and 4/4):
- Split the monolithic "Enrich source downloads" patch into two focused
  patches: ecosystem PURLs (patch 3, bbclass-only) and Git download
  enrichment (patch 4, spdx30_tasks.py additions-only)
- Removed ALL extraneous changes: formatting, comment removals,
  blank-line deletions, variable removals, and off-topic refactors
- Fixed go-mod.bbclass duplicate SPDX_PACKAGE_URLS line
- Reverted pypi.bbclass UPSTREAM_CHECK_PYPI_PACKAGE change
- Removed the else-branch that copied recipe ecosystem PURLs to
  non-git download files (per Joshua's feedback)
- Reverted do_create_spdx -> do_create_package_spdx change in
  collect_build_package_inputs
- Reverted bb.note -> bb.fatal for missing SPDX providers
- Restored all removed TODO comments and blank lines
- Patches 2-5 are now strictly additions-only (0 deletions)
- Tests unchanged (additions-only, all 12 master tests preserved)

Stefano Tondo (5):
  spdx30: Add configurable file exclusion pattern support
  spdx30: Add supplier support for image and SDK SBOMs
  spdx30: Add ecosystem PURLs for recipe classes
  spdx30: Add Git version and PURL to source downloads
  oeqa/selftest: Add tests for source download enrichment
