It works on Intel machines as well as recent machines powered by Apple
Silicon. QEMU 6.2.0 is needed for Apple Silicon support.
* qemu: Support mode option for dirtyrate calculation
Introduce ``virDomainDirtyRateCalcFlags`` as parameter of
``virDomainStartDirtyRateCalc``, which is used to specify the mode of
dirty page rate calculation.
Add ``--mode`` option to ``virsh domdirtyrate-calc``, which can be
either of the following 3 options:
``page-sampling, dirty-bitmap, dirty-ring``.
Add ``calc_mode`` field for dirtyrate statistics retured by
``virsh domstats --dirtyrate``, also add ``vCPU dirtyrate`` if
``dirty-ring`` mode was used in last measurement.
* **Improvements**
* packaging: sysconfig files no longer installed
