[OE-core][PATCH v2 0/5] Implement SPDX for deploy tasks

[Joshua Watt <jpewhacker@gmail.com>]

The SPDX use case for file system image has been well defined since SPDX
was first implemented, however there has always been a desire to also
express SPDX output for other non-image deliverables (primarily, those
that have a do_deploy task or similar). These types of tasks cannot
easily use the traditional method of having a separate SPDX task that
runs to create their SPDX output as this causes lots of problems with
the way dependencies are specified. Instead, it is desirable for these
tasks to directly produce SPDX output that can be consumed by other
tasks that depend on them.

This patch series adds support for this. Any sstate task that starts
with "do_deploy" can now be added to the SPDX_DEPLOY_TASKS list and it
will run a postfunc to generate SPDX output that describes what is being
deployed. For classical do_deploy tasks, this is setup to be easy by
automatically capturing all the deployed output files in the SPDX data,
but other tasks can be added as well.

Finally, the do_create_image_spdx task is removed and replaced with a
SPDX deploy postfunc using this new system. This means that any task
that depends on do_image_complete will automatically also get the SPDX
output for the image, simplifying the dependency handling.

V2: Fixed SPDX documents missing at SBoM creation time when the
documents were not a direct dependency of the SBoM, and were present in
a sstate object. Previously, these sstate objects were not restored
because they were "covered" by the later sstate tasks, but now they are
restored if they are depended on by a task that creates SPDX output.

  spdx: Add ability for deploy tasks to create SPDX
  classes-global/sstate: Keep SPDX generating setscene dependencies
  Add SPDX deploy tasks to various recipes
  spdx: Replace do_create_image_spdx with deploy task
  grub-efi: Change to MACHINE_ARCH
