Documentation: Clarify palette/font/stylesheet inheritance/propagation
Palette and font changes made by a style sheet are propagated to
existing widgets and their children at change time.
Palette and font changes made by setPalette() and setFont() are
inherited by all existing and future children of the widget to which the
call was made.
Clarify this in the documentation.
Fixes: QTBUG-122588
Pick-to: 6.5 6.2 5.15
