Windows: Create one QPlatformCursor per screen.

The pixmap-based cursors and some of the standard cursors we
create from resource pixmaps need to be separated per screen.

Use a QScopedPointer containing the per-screen cursor instead
of the previously used QSharedPointer containing the cursor
shared by all screens.
