[PATCH qemu-server v3 02/12] helpers: drop local version helpers in favor of pve-common

[David Riley <d.riley@proxmox.com>]

Drop the local `version_cmp` and `pvecfg_min_version` implementations
and update call sites to use the centralized tools module from
pve-common.

Prepare for #7294 to consolidate version checking logic across
components.
