Use QML_ELEMENT macro instead of qmlRegister* for mediaplayer 

Updated the MediaPlayer example to use compile-time QML registration via
the QML_ELEMENT macros instead of qmlRegisterSingletonType. This aligns
the example with modern Qt 6 best practices and improves startup
performance and tooling integration.

Pick-to: 6.9 6.8
Task-number: QTBUG-136712
