iOS: Switch backingstore to use raster paint engine, not GL
Now that more of the raster operations are NEON-optimized this should
be acceptable. The switch enables antialiased drawing, and makes iOS
in line with other platforms in having QBackingStore backed by a QImage.
The use of QImage also allows us to remove code from the backingstore
implementation that was only needed to support the composeAndFlush
code path.
The common parts of a raster backingstore implementation have been
factored out into QRasterBackingStore in platformsupport, which can
be shared with more platforms in the future.
[ChangeLog][iOS] QBackingStore now uses the raster paint engine
instead of the OpenGL paint engine, enabling improved antialiased
drawing. In case of performance regressions, the old code path
can be enabled by setting the window's surface type to
QSurface::OpenGLSurface.
