QML Compiler statistics fail once a single module uses "--only-bytecode"

If you have a project with multiple QML modules you want to use the "all_aotstats" target to get statistics for QML compilation as documented here:

https://doc.qt.io/Qt-6/qtqml-qml-script-compiler.html#obtaining-statistics-about-the-compilation-of-functions-and-bindings

Once one of the modules in your application uses the "--only-bytecode" flag for qmlcachegen, the aostats can't be created anymore.

Expected outcome:

The all_aostats target should still work and list the compilation statistics for all files it actually compiled.
