[OE-core][dunfell][PATCH v2 0/5] Backport SPDX Support

[Joshua Watt <jpewhacker@gmail.com>]

Backports support to creates SPDX during the build from the master
branch, with a few changes to make it compatible with dunfell.
Primarily, the SPDX data is compressed with gzip instead of zstd to
prevent needing the zstd host tools on the older distros supported by
dunfell

v2:
    Fixed SPDX symlinks still using .zst instead of .gz extension

Joshua Watt (5):
  classes/create-spdx: Backport
  classes/package: Add extended packaged data
  licenses: Add GPL+ licenses to map
  create-spdx: Use gzip for compression
  classes/package: Use gzip for extended package data
