scarthgap: narrow CI and LAYERSERIES_COMPAT to scarthgap-only

First commit on the new scarthgap release branch. Per the
meta-vscode release-branch policy: parse-oe-core job is dropped
(poky covers scarthgap), the parse matrix collapses to just
scarthgap, LAYERSERIES_COMPAT narrows to a single series, and
the build job uses the matching poky branch. main keeps the
broader multi-release matrix.
