WinRT QPA: Fix crash in QWinRTBackingStore::flush()
QWinRTBackingStore::flush() was not considering the possibility
that the supplied region may fall partially outside the bounds
of the paint device. This resulted in possible accesses to invalid
memory addresses, causing a crash. This bug was exposed by an update
in ANGLE that was causing a crash when running tst_QTableView::bigMode
with a small screen size. With this fix the function will use the
intersection of the supplied region with the paint device bounds.
