[REG 6.8.2->6.8.3] Handling of custom scheme URL is broken

Registering custom scheme URLs using  QDesktopServices::setUrlHandler() no longer works on Android with Qt 6.8.3. Previous version Qt 6.8.2 did not show any issues.
I've identified the commit https://codereview.qt-project.org/c/qt/qtbase/+/618970 as the cause for this problem.

As far as my understanding goes, the issues stems from QAndroidPlatformServices::handleNewIntent() not being called, as it will only be instantiated from QDesktopServices::openUrl() when the services() method is called.

Previously, QAndroidPlatformServices::handleNewIntent() would try to open the custom scheme URL via the QDesktopServices which called the custom handler registered with QDesktopServices::setUrlHandler().
