The separate sample package is now built before the verify and imported into the
throwaway project (like a dependency package), so the sample's scripts are
actually compiled -- exercising the real shipped artifact including the ~-strip.
module.json "sample" may now be {path, packages}, where packages are the UPM deps
the sample needs (TextMeshPro/uGUI, Input System) added to the verify scaffold.

Editor InitializeOnLoad script that adds the module's scripting define so other
modules (e.g. SOVariant) can gate optional integration code behind
#if MODULE_SCRIPTABLE_OBJECT_DATABASE_EXIST.

Bumps to 2.2.2 so the MODULE_SCRIPTABLE_OBJECT_DATABASE_EXIST define script (added
in the previous commit) reaches consumers. Syncs release.py to the latest (adds
the resolver core-vs-Samples fix).

The define script used namespace ...ScriptableObjectDatabase.Editor, whose nested
'Editor' segment shadowed the UnityEditor.Editor base type in the module's editor
classes (CS0118). Move it to ArcaneOnyx.ModuleDefines.
