+Subject: fix: mas gate private enterprise APIs
+
+Beginning in Electron 15.2.0, Chromium moved several formerly public
+APIs into the AreDeviceAndUserJoinedToDomain method. Using these APIs
+in a MAS build will result in rejection from the Apple Store. This
+patch gates those APIs to non-MAS builds to comply with Apple
+Store requirements, and returns the default state for MAS builds.
