qdev: all globals are now user-provided 

All globals are now either provided via -global or through -cpu
features (CPU features are implemented by registering globals).

If the global isn't being used, it should warn in either case.

We can thus consider that all global_props are "user-provided"
globals. No need to track this per-globals anymore.
