Make qmp_pc_dimm_device_list() return sorted by start address
list of devices so that it could be reused in places that
would need sorted list*. Reuse existing pc_dimm_built_list()
to get sorted list.
While at it hide recursive callbacks from callers, so that:
qmp_pc_dimm_device_list(qdev_get_machine(), &list);
could be replaced with simpler:
list = qmp_pc_dimm_device_list();
* follow up patch will use it in build_srat()

It may need to treat PC-DIMM and NVDIMM differently, e.g., when
deciding the necessity of non-volatile flag bit in SRAT memory
affinity structures.
NVDIMMDeviceInfo, which inherits from PCDIMMDeviceInfo, is added to
union type MemoryDeviceInfo to record information of NVDIMM devices.
The NVDIMM-specific data is currently left empty and will be filled
when necessary in the future.
It also fixes "info memory-devices"/query-memory-devices which
currently show nvdimm devices as dimm devices since
object_dynamic_cast(obj, TYPE_PC_DIMM) happily cast nvdimm to
TYPE_PC_DIMM which it's been inherited from.

and just write this as
'data': { 'dimm': 'PCDIMMDeviceInfo',
'nvdimm': 'PCDIMMDeviceInfo' }
If, down the road, you want to add data members to one but not both of
the branches, we can add a new (sub-)type at that time, and it won't
break backwards compatibility.

ACPI 6.2A Table 5-129 "SPA Range Structure" requires the proximity
domain of a NVDIMM SPA range must match with corresponding entry in
SRAT table.
The address ranges of vNVDIMM in QEMU are allocated from the
hot-pluggable address space, which is entirely covered by one SRAT
memory affinity structure. However, users can set the vNVDIMM
proximity domain in NFIT SPA range structure by the 'node' property of
'-device nvdimm' to a value different than the one in the above SRAT
memory affinity structure.
In order to solve such proximity domain mismatch, this patch builds
one SRAT memory affinity structure for each DIMM device present at
boot time, including both PC-DIMM and NVDIMM, with the proximity
domain specified in '-device pc-dimm' or '-device nvdimm'.
The remaining hot-pluggable address space is covered by one or multiple
SRAT memory affinity structures with the proximity domain of the last
node as before.

QEMU now builds one SRAT memory affinity structure for each PC-DIMM
and NVDIMM device presented at boot time with the proximity domain
specified in the device option 'node', rather than only one SRAT
memory affinity structure covering the entire hotpluggable address
space with the proximity domain of the last node.
Add test cases on PC and Q35 machines with 4 proximity domains, and
one PC-DIMM and one NVDIMM attached to the 2nd and 3rd proximity
domains respectively. Check whether the QEMU-built SRAT tables match
with the expected ones.
The following ACPI tables need to be added for this test:
tests/acpi-test-data/pc/APIC.dimmpxm
tests/acpi-test-data/pc/DSDT.dimmpxm
tests/acpi-test-data/pc/NFIT.dimmpxm
tests/acpi-test-data/pc/SRAT.dimmpxm

tests/acpi-test-data/q35/NFIT.dimmpxm
tests/acpi-test-data/q35/SRAT.dimmpxm
tests/acpi-test-data/q35/SSDT.dimmpxm
New APIC and DSDT are needed because of the multiple processors
configuration. New NFIT and SSDT are needed because of NVDIMM.
