parser: Move QML runtime elements to qmlstructure.js

Code moved to qmlstructure.js wasn't inherited from UglifyJS, so the
copyrights are updated accordingly.

To see which exact code was based on UglifyJS, see the
https://github.com/qmlweb/qmlweb-parser repository, which contains the
parser rebased on the original UglifyJS version.
