[PySide] setLayout and setCentralWidget when using true_property

[Christian Tismer-Sperling]

Hi Matt,

this looked also weird for me (I made these features) and I was tempted
to change the centralWidget to a property, but we decided to stay
compatible with the Qt documentation, where you can find this as normal
getter and setter functions.

I hope this changes sometimes soon. There is also some effort to
support this information in the Qt for Python docs.

What you can do immediately:

Use the pyi generator with true_property and snake_case enabled.
Then you get the properties listed in QtCore.pyi etc.

   <your-bin-folder>/pyside6-genpyi all --feature snake_case \
                                                  true_property

Cheers -- Chris
