virQEMUCapsProbeQMPDeviceProperties: Add per-property callbacks
QEMU-5.0 added 'default-value' field for any applicable property returned by 'device-list-properties'. Add an optional callback for any device property definition which will allow detection of features and default values based on this new data. This unfortunately means that the description of properties had to move from the slightly-too-generic 'struct virQEMUCapsStringFlags' to a new type (virQEMUCapsDevicePropsFlags) which also has the callback property and the corresponding change in the initializers.
