qemuhotplugtest: test setvcpus async downscale

Add async unplug coverage for the setvcpus count-based path.

The test downscales an x86 domain by multiple hotpluggable vCPU entities,
verifying the pending XML before completion, the final XML after DEVICE_DELETED
processing, and one vcpu-removed event for each removed vCPU.
