feat(skd): modify-parameter operation, availableValues/denyIncompleteValues support

- skd-edit: new modify-parameter operation — set use, denyIncompleteValues, add availableValue entries to existing parameters
- skd-compile: availableValues array and denyIncompleteValues in parameter JSON DSL
- Auto-detect DesignTimeValue type for reference values in availableValue entries
