QHeaderView - add maximum section size

When we auto resize it is handy to be able to limit the maximum
size (just like the minimum size).

[ChangeLog][QtWidgets][QHeaderView]A maximumSize for sections
has been introduced. The maximum section size is by default
the largest possible section size which in Qt 5.2 has been
limited to 1048575 pixels.

Task-number: QTBUG-4346
