"Disables QML Debugging" shows for building Qt 6 applications when Qt Quick Compiler is enabled

When enabling Qt Quick Compiler for building a debug version of a QMake project with a Qt 6 version, the "Disables QML debugging. QML profiling will still work" warning message shows. However, QML debugging is still enabled, NOT Disabled. 

Steps to reproduce:

• Open the attached QMake project in Qt Creator 15.0.0
• Go to Projects > Build & Run and select Desktop Qt 6.8.1 kit
• On the same screen, go to Build Settings > General > Qt Quick Compiler and select "Enable"
• The warning message shows next to the setting box. The screenshot is attached.
• Build the project in debug mode
• Open main.qml, and set a break point at line 9
• Hit F5 to run the app
• The app stopped at the break point
