User can select ui.qml or qml generation

When metadata from Figma is importer to QDS, there should be an option in the import dialog to tell importer to generate UI.QML or QML files. 

If use chooses pure QML there should be indication that re-imports from Figma and such won't work like with the UI.QML and if user adds functionality to the qml components - QDS might not be able to render them.
