Add scripts which generates Qt plugins and QML imports preload lists, for use with the "preload" functionality form qtloader.js. The preload lists downlad plugins and imports from $QTDIR/ to /qt/ at application load time, where $QTDIR is configurable using the qt.qtdir qtloader configuration property (set to "qt" by default). Sample directory structure: app.html app.js qtloader.js qt_plugins.json [generated] qt_qml_imports.json [generated] qt -> /path/to/qt [symlink] The json files are generated by the scripts in this commit. app.html configures qtloader.js to use the json files as preload lists, which instructs it to preload from "qt", which again is a symlink to or a copy of the Qt installation. Pick-to: 6.6 Task-number: QTBUG-63925 Change-Id: I53bd197f22057dbb70e9a9bee43b9d9b969aa072 Reviewed-by: Morten Johan Sørvig <morten.sorvig@qt.io>
