Add support for the POWER11 CPU model in libvirt ppc64 CPU map. This
allows libvirt to recognize and handle guests that specify POWER11 as
the target CPU model when running on recent Power systems supporting
this architecture.
The addition includes:
- A new src/cpu_map/ppc64_POWER11.xml definition file describing the
features and flags for POWER11 CPUs.
- Updates to src/cpu_map/index.xml and build system (meson) to include
the new model.
- Test updates to qemucapabilitiesdata and qemuxmlconfdata to reflect
the presence of POWER11 in supported CPU models.
- Adjustments to existing test XMLs to fix CPU model expectations
and avoid mismatches during validation against QEMU output.
With this change, users can specify <model>POWER11</model> in guest CPU
configuration and have libvirt map it correctly to the corresponding
QEMU CPU model and capabilities.
Tested with:
- QEMU 10.0.0 on POWER11 host system
- Validated with updated domain capabilities and qemu capabilities tests
