[Bug]: PySide6 6.4.0 and FigureCanvasQTAgg Combability #24175
Description
Bug summary
Using the latest PySide6 version (6.4.0) and Matplotlib version (3.6.1), it is not possible to import FigureCanvasQTAgg. It seems that the whole Qt backend breaks.
Code for reproduction
from matplotlib.backends.backend_qtagg import FigureCanvasQTAggActual outcome
File "C:\Users\Mustafa\Desktop\Projects\test_project\test.py", line 1, in <module>
from matplotlib.backends.backend_qtagg import FigureCanvasQTAgg
File "C:\Users\Mustafa\Desktop\Projects\test_project\.venv\lib\site-packages\matplotlib\backends\backend_qtagg.py", line 12, in <module>
from .backend_qt import QtCore, QtGui, _BackendQT, FigureCanvasQT

The problem is an unexpected change in pyside6 in how they handled their enums. This was fixed in #24158 and well be in mpl 3.6.2.
