Allow creating memory regions that are managed by QOM and freed with
their owner as it is already documented and implemented but there was
no way to use it.

v6:
- rebase on master
- do not export memory_region_set_ops in patch 1 (will try different
way in ati-vga for this)

v5:
- rebase on master
- add patch to export memory_region_set_ops (needed for ati-vga endian
switch)

v4:
- rebase on latest version of clean up series:
Based-on: cover.1772924151.git.balaton@eik.bme.hu

v3:
- based on split off clean up series
- convert xtfpga from nomigrate as this has no migration compatibility
issue

v2:
- rebase on master
- update documentation
- use these function to fix some leaks (there may be more, e.g. in
hw/pci-host/bonito but I leave that for later and/or others)
