FROMLIST: virt: geniezone: Reduce blocked duration in hypervisor when destroying a VM

Reduce the blocked duration in the hypervisor when destroying a VM
by splitting a single hypercall into multiple calls. Previously, the
hypervisor could be blocked for an extended period when destroying a VM, as
the entire process was handled in a single hypercall. This could lead to
performance degradation because the scheduler does not have chances to
schedule other tasks when the hypercall is processing by the hypervisor.

By splitting the destruction process into multiple smaller hypercalls,
significantly reduce the blocked duration in the hypervisor. Additionally,
making the amount of each call adjustable provides flexibility to optimize
the process based on different workloads and system configurations.
