examples: Turn most QPainter instances into context managers
After the new context manager is in place, most of
the examples benefit from moving QPainter into a
`with` statement.
The comments concerning PyPy could be removed, again.
[ChangeLog][PySide6] The examples are updated to use the new
context manager for QPainter.
