Generic property support for platform windows

QPlatformNativeInterface can now contain generic window
properties in a QVariantMap, to facilitate communication
with the compositor and clients for certain platforms.
When window properties change, a signal is emitted from the
respective QPlatformNativeInterface instance. The properties
are intended to be read/writable from both client and server.
