Qt: loading stale QML files bug

Changes on QML files do not seem to regenerate the resources. Should not we only put the qmlcachegen'd version in the binary? Is it also necessary to put the raw qml files in resources?
Loading QML files by URI does not seem to respect the changes in the QML file, considering that qmlcachegen runs again on that file.

I'm not sure if this is introduced with Qt 6 or was the case before.

Ping @chub.
