Add a new layer meta-gsj to meta-quanta.

Tested: This commit included the basic machine config
        and package group setting for project GSJ.
        And it could build successfully with meta-nuvoton fix
        (https://gerrit.openbmc-project.xyz/#/c/openbmc/openbmc/+/17719/).
        But the built image cannot run on EVB now,
        it is because the image generate script still not ready yet.

(From meta-quanta rev: e08538d3df34128ef92c0593c1556931e62c614a)
