Doc: QtCore: Fix documentation issues

* Add module header wrapper that loads the real QtCore header and
    qandroidextras_p.h to generate docs for those types
  * Add missing dummy typedefs to doc/include/jni.h
  * Use the correct \namespace name (QtAndroidPrivate) and mark it
    as \preliminary
  * Add missing 'const' specifier for Q[Untyped]Bindable methods
  * Drop documentation for removed method QProperty::markDirty()
  * qmath.h: Fix \fn commands for qFloor(), qCeil()
  * QHashSeed: Drop incorrect usage of \relates

-  \fn template <typename T> void QProperty<T>::markDirty()
-
-  Programatically sets the property dirty. Any binding which depends on it will
-  be notified.
-  This can be useful for properties which do not only depend on bindable properties,
-  but also on non-bindable properties or some other state.
-
-  For example, assume we have a \c Circle class, with a non-bindable \c radius property
-  and a corresponding \c radiusChanged signal. We now want to create a property for a
-  cylinders volume, based on a height \c QProperty and an instance of Circle. To ensure
-  that the volume changes, we can call setDirty in a slot  connected to radiusChanged.
-  \code
-  Circle circle;
-  QProperty<double> height;
-
-  QProperty<double> volume;
-  volume.setBinding([&]() {return height * std::pi_v<double> * circle.radius() * circle.radius()};
-  QOBject::connect(&circle, &Circle::radiusChanged, [&](){volume.markDirty();});
-  \endcode
-
-  \note Binding to a QObjectBindableProperty's signal does not make sense in general. Bindings
-  across bindable properties get marked dirty automatically.
