The API reduces the amount of manual plumbing required to offer a
conceptual property through the traditional setter/getter API as well as
through QProperty<T> API. Since the latter would require inlining the
type and thus making it impossible to add new properties without
breaking binary compatibility, this patch introduces a fake API that
behaves similar but does not contain the property by value.

Recently the moc learned that Q_PROPERTY(int x ...) can mean that "x" is
implemented as QProperty and then allows installing bindings, etc. -
this works by scanning the same class' members.
For our own use of QProperty, we need to place the QProperty member
itself into the d-pointer to be able to maintain the ability to add new
properties without breaking binary compatibility. That however means
that moc can't know that a certain property is backed by QProperty - we
don't scan the members of the private class.
As a workaround, this change enables the syntax where the property type
used in Q_PRIVATE_PROPERTY may be wrapped with QProperty<T>.
In addition this patch fixes the compilation of such declared properties
by ensuring the accessor prefix (t->$accessor) is applied also for the
QProperty related meta call variants.

This requires mostly making moc a bit more permissive, which has the
advantage that it also simplifies the code a little bit.
The newly added test case demonstrates how to connect such a property
with a change signal.
One test case needed to be changed regarding the callback as the
publicProperty member now has a (permanent) observer and therefore
re-assigning the binding will re-evaluate it as the value might have
changed.

This patch fixes the QMetaObject::superClass hierarchy for Q_GADGETs
that inherit from a template which in turn inherits another Q_GADGET.
One common scenario where this is applied is for the CRTP. Without this
patch, moc would stop at the template and then sets the superClass
QMetaObject to a nullptr. For QObjects this works, since there moc knows
that every child must by definition inherit QObject. In order to support
this for Q_GADGETs too, we defer the judgment about the availability
of a staticMetaObject in the base class to compile time through the
existing QtPrivate::MetaObjectForType<Base>::value() helper.
[ChangeLog][QtCore][moc] Moc now correctly sets a non-null
QMetaObject::superClass for Q_GADGETs that inherit from a template which
inherits another Q_GADGET.

Windows has a problem relating to cross-DLL variable relocations: they
are not supported. Since QMetaObject's link to the parent class is done
via a pointer, every QMetaObject in a DLL or in the EXE that derives
from a class from another DLL (such as QObject) will be dynamically
initialized.
This commit changes the meta object pointers in QMetaObject::d from raw
pointers to a wrapper class SuperData, which is almost entirely source-
compatible with the pointer itself. On all systems except for Windows
with Qt 6, it's binary compatible with the current implementation.
But for Windows with Qt 6, this commit will store both the raw pointer
and a pointer to a function that returns the QMetaObject, with one of
them non-null only. For all meta objects constructed by moc, we store
the function pointer, which allows the staticMetaObject to be statically
intialized. For dynamic meta objects (QMetaObjectBuilder, QtDBus, QtQml,
ActiveQt), we'll store the actual raw pointer.
[ChangeLog][QtCore][QMetaObject] Some internal members of the
QMetaObject class have changed types. Those members are not public API
and thus should not cause source incompatibilities.
The macro QT_NO_DATA_RELOCATION existed in Qt 4 but was called

A recurring problem with the Q_NAMESPACE macro is that it declares
an object (staticMetaObject) in the surrounding namespace. That
object lacks any export/import qualification to make it usable
with shared libraries.
Introduce therefore another macro to work around this issue, allowing
the user to prefix the object with an exporting macro, f.i. like this:
Q_NAMESPACE_EXPORT(Q_CORE_EXPORT)
The old macro can simply then be rewritten in terms of this new one,
supplying an empty export macro.
Note that NOT passing an argument to a macro expecting one is well
defined behavior in C99 -- the macro will expand an empty token.
Of course, MSVC doesn't like this and emits warnings. As a
workaround, use a variadic macro.
[ChangeLog][QtCore] Added the new Q_NAMESPACE_EXPORT macro. It
can be used just like Q_NAMESPACE to add meta-object information
to a namespace; however it also supports exporting of such
information from shared libraries.
[ChangeLog][Potentially Source-Incompatible Changes] Prefixing
Q_NAMESPACE with an export macro may no longer work. Use the new
Q_NAMESPACE_EXPORT macro for that use case.
