Qt Gradle Plugin does not build a multiabi AAR

Steps to reproduce:

1. Create new Android project
2. Add Qt Gradle Plugin to the project
3. Use /foobar/Qt/6.8.0 as qtPath
4. Select a QML project as qtProjectPath
5. Build and deploy the app to emulator (x86_64)
6. App crashes with > FATAL EXCEPTION: qtMainLoopThread
   Process: com.example.qtquickview_java, PID: 20247

More investigations:

The build folder for the Qt project is under build/qt_generated. The target of the project is aar, so the output should be an .aar file. The AAR files should include app library (.so) and all other Qt libraries from all installed ABIs. But it only include arm64_v8a libraries.

It seems that QT_ANDROID_BUILD_ALL_ABIS=ON is not properly passed during cmake config.
