[Background: based upon Peter's feedback at
 https://lists.gnu.org/archive/html/qemu-devel/2026-06/msg07717.html I realised
 that what we really need are object_class_property_add_*_ptr() equivalents to
 the existing object_property_add_*_ptr() functions to make it easier to
 convert existing properties.

 There are actually existing functions with these names that are already in use
 but after observation these are really static properties, so these are renamed
 to aid porting object props to class props, as well as making the difference
 clearer.]

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

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.

v2:
- Add object_class_property_add_*_ptr() functions matching the existing
  object_property_add_*_ptr() functions for class functions

- Rework patch to use new functions instead of manually adding get/set
  functions as part of the conversion

- Ignore existing R-Bs since this approach is quite different to v1

- Rebase onto master
