Since the use of object props is effectively deprecated, here is an attempt
to convert all use of object props in hw/i386 to class props. The eventual
aim is to continue working through the codebase, removing all remaining uses
of object props.

In order to facilitate the conversion of alias properties, this series
introduces a couple of new QOM functions: object_class_property_add_alias()
and object_property_set_alias() to declare the property and to set it within
an instance accordingly. This implementation is hugely inspired by the
existing link class property code: many thanks to Marc-André for doing this
initial work.

The series is lightly tested: it passes "make check", GitLab CI and some
simple local tests. I'm mostly interested for feedback on the conversion
strategy, and to get a feel for the best way to merge this series since once
the basic conversion patterns are in place, the same patterns can be applied
elsewhere and it would be good to minimise the merge window for such changes.
