No logic change. Only movement.

a4f136188c hv: vm: Move reset_vm to common scope
Move reset_vm to common scope and remove unused reset_mode.

The reset_mode in x86 reset_vm code is simply used as an if condition
on whether the prepare_os_image should be executed. The entire
if body will never be true as we don't support resetting Service VM
without resetting ACRN hypervisor. To reset Service VM, the only
way is through a platform reset. Therefore the prepare_os_image
action will never be called. Delete this action.

Once the if condition and prepare_os_image action is deleted,
the input parameter "mode" is useless. Delete that too. The reset_vm
API in ACRN is simply a "warm reset". It does not need to take
input.

e0130295b5 hv: vm: Move shutdown_vm to common scope
The shutdown_vm is renamed to destroy_vm,
and introduce arch_deinit_vm as mandatory arch public API.

The original shutdown_vm checks if all VMs are shutting down,
and shutdown platform if no other VMs are running.

This logic is moved to the caller of original shutdown_vm
except hypercall, as we post-launched VM shutdown should not
trigger platform shutdown.

8cb6d01810 hv: vm: Move start_vm to common scope
start_vm is moved to common scope calling
arch_vm_start_bsp, which is a mandatory API
for all archs.

3ebedf7539 hv: vm: Get rid of prepare_vm
The logic in prepare_vm can be embedded to launch_vms
and create_vm with better readability.

The movement does not change original logic.

6a4ba8116c hv: vm: Move launch_vms and create_vm to common scope
launch_vms and create_vm need to be moved together as both of
them reference file-static structures. All related structures
and helpers accessing structures are also moved.
