QPagedPaintDevice - Use QPageSize and QPageLayout

Use new QPageLayout and QPageSize class to store and convert page sizes
and layouts consistently.  Extend the PageSize enum to match
QPage::PageSize.

Note that public setters/getters cannot be added as virtuals would break
BIC, but without virtuals the derived classes would break.  Instead an
internal api is provided and the derived classes will need to
implement identical api to manipulate it.

[ChangeLog][QtGui][QPagedPaintDevice] Paged paint devices such as
QPrinter and QPdfWriter now support all Postscript standard page sizes.
