qFuzzyCompare() overloads not available

The only overload available for qFuzzyCompare() is the one for `double` provided by QtCore. The other overloads are visible in the `typesystem_gui_common.xml`, but they do not appear to result in any entries in the QtGui.pyi file.

To reproduce, do a clean install of PySide (here using PySide2 but also possible with PySide6):

$ python -m venv temp.venv
$ source temp.venv/bin/activate
$ pip install --upgrade pip setuptools numpy PyOpenGL
$ pip install --index-url=http://download.qt.io/official_releases/QtForPython/ --trusted-host download.qt.io shiboken2 pyside2 shiboken2_generator

Using the overload for `double` works:

$ python -c "from PySide2.QtCore import *; print(qFuzzyCompare(0.0, 0.0))"
True

But the overload for `QMatrix4x4` does not:

$ python -c "from PySide2.QtGui import *; print(qFuzzyCompare(QMatrix4x4(), QMatrix4x4()))"
Traceback (most recent call last):
File "<string>", line 1, in <module>
NameError: name 'qFuzzyCompare' is not defined
$ python -c "from PySide2.QtCore import *; from PySide2.QtGui import *; print(qFuzzyCompare(QMatrix4x4(), QMatrix4x4()))"
Traceback (most recent call last):
File "<string>", line 1, in <module>
TypeError: 'PySide2.QtCore.qFuzzyCompare' called with wrong argument types:
PySide2.QtCore.qFuzzyCompare(QMatrix4x4, QMatrix4x4)
Supported signatures:
PySide2.QtCore.qFuzzyCompare(float, float)

A quick grep on the installed files shows this:

So it appears that the function signature is made visible to the typesystem, but it does not result in any generated bindings for the QtGui overloads.
