Make all global and compat properties available before the first objects

This is the probe/preinit iterator, might be good to keep it simple to only
make the decision of choosing one accel, then move this line over to
configure_accelerators() at the end.
It's actually simpler to leave it here. Hoisting
object_set_accelerator_compat_props
would require extra code to derive the ac parameter.
