feat(skd): use=false на selection items

SelectedItemField и SelectedItemAuto могут иметь <dcsset:use>false</dcsset:use>
— отключённое поле выборки. Раньше игнорировалось при roundtrip.

DSL расширения:
- selection item object form: { field, use: false, title?, viewMode? }
- новый объект для отключённого Auto: { auto: true, use: false }

Decompile переходит в object form если есть use=false (помимо title и
viewMode); compile эмитит <use>false</use> в начале item (XML-порядок).
