Remove QtAndroidExtras module and add note about its state in Qt 6HEADdev

The JNI utilities (i.e. QJniObject, QJniEnvironment) are already under
qtbase as public APIs.

Permission handling is now under QCoreApplication::{check,request}Permission
and QPermission namespace.

Some of the QtAndroid namespace functions are now under QNativeInterface's
QAndroidApplication, this includes:
* sdkVersion()
* hideSplashScreen()
* context() and isActivityContext()
* runOnAndroidMainThread()

The remaining APIs are now moved as private APIs under qtbase
ee05af296f65e240f64db6470cdddafbddbf2fa3. That is until we add
new cross-platform APIs to replace their functionalities like
Intents handling, starting activites and working with Services.

-    \title Qt JNI Messenger
-    \ingroup examples-qtandroidextras
-    \example jnimessenger
-    \brief Demonstrates communication between Java code and QML or C++ using NJI calls.
-
-    \image jnimessenger.png
-
-    This example demonstrates how to add a custom Java class to an Android application, and
-    how to both call it from C++ and call C++ functions from Java using the JNI convenience
-    APIs in the Qt Android Extras module. The application UI is created by using Qt Quick.
-
-    When clicking the send button, a message will be sent from QML to Java class though
-    the C++ class and a log of that is shown in the screen view. Logs also can be seen
-    from the Android logcat of the messages being exchanged, which would be similar to:
-
-    \badcode
-        I System.out: This is printed from JAVA, message is: QML sending to Java: Hello from QML
-        D libjnimessenger_armeabi-v7a.so: qml: QML received a message: Hello from JAVA!
-    \endcode
-
-    \include examples-run.qdocinc
-
-    \section1 Calling Java Methods from C++ Code
-
-    We define a custom Java class called \c JniMessenger in the JniMessenger.java file:
-
-    \quotefromfile jnimessenger/android/src/org/qtproject/example/jnimessenger/JniMessenger.java
-    \skipto org.qtproject.example.jnimessenger
-    \printuntil /^\}/
-
-    \note The custom Java class can extend other classes like QtActivity, Activity or any
-    other Java class.
-
-    In the jnimessenger.cpp file, we call the function \c printFromJava(String message)
-    by first creating a \c QAndroidJniObject for the Java String that we want to send
-    and then invoking a JNI call with \c callStaticMethod<>() while providing the method
-    signature:
-
-    \quotefromfile jnimessenger/jnimessenger.cpp
-    \skipto void JniMessenger::printFromJava
-    \printuntil }
-
-    That call will then execute the following from Java side, which would print the
-    message to the \c System.output.
-
-    \quotefromfile jnimessenger/android/src/org/qtproject/example/jnimessenger/JniMessenger.java
-    \skipto public static void printFromJava
-    \printuntil );
-
-    \section1 Calling QML/C++ Functions from Java Code
-
-    Directly after that, our native function \c callFromJava(String message) will be
-    called, which would be then handled from C++ side. Note, that this method has
-    to be defined as \c native at the top of the Java class as:
-
-    \code
-        private static native void callFromJava(String message);
-    \endcode
-
-    To be able to call C++ functions from Java, in our C++ class JniMessenger.cpp,
-    we need to define those functions using \c RegisterNatives() as follows:
-
-    \quotefromfile jnimessenger/jnimessenger.cpp
-    \skipto JNINativeMethod
-    \printuntil }
-
-    (See \l{Java Native Methods} for more details).
-
-    We would need to register the functions' signatures in \c methods[], which have
-    the name in Java class, then its parameters and return types, then the function
-    pointer in the C++ code.
-
-    \code
-        JNINativeMethod methods[] {{"callFromJava", "(Ljava/lang/String;)V", reinterpret_cast<void *>(callFromJava)}};
-    \endcode
-
-    This would insure that our C++ function is available from within the Java call.
-    Now, that function could simply print the message it received from Java to
-    the debug log, but we want to forward the received message to the QML components
-    so that it gets displayed in our text view, so we get:
-
-    \quotefromfile jnimessenger/jnimessenger.cpp
-    \skipto static void callFromJava
-    \printuntil }
-
-    Now, we need to implement the necessary \c Connections in the QML code to receive
-    the message from C++, which we would print into the \c Text view with the id \c messengerLog:
-
-    \quotefromfile jnimessenger/main.qml
-    \skipto Connections
-    \printuntil /^\ {4}\}/
