feat: allow Cloud Config for Windows guests (Cloudbase-Init) (#984)
* feat(vm): allow Cloud Config for Windows guests

Currently the Cloud Config editor is completely hidden when a VM's
OS Type is set to Windows, and no `cloudinitdisk` volume or secret
is written to the VM spec even if the user has entered content.

This blocks a common Windows-on-Harvester workflow: using
Cloudbase-Init to run first-boot configuration (install VMDP,
enable OpenSSH server, add authorized_keys, join a domain, run
`runcmd` steps, etc.). Users on Windows today have to hand-edit the
VM YAML after creation to attach a cloudinitdisk, which is fragile
and undiscoverable.

Changes:
- Remove the `v-if="!isWindows"` on the CloudConfig component so
  the editor is available for every OS type. The Sysprep editor
  continues to render only for Windows, so Windows now gets both
  panels; Linux is unchanged.
- Drop the `if (!this.isWindows)` guard around the cloudinitdisk
  volume serialization so the disk is attached whenever the user
  provided user-data or network-data, regardless of OS.
- Drop the `|| this.isWindows` early-return in `saveSecret` so the
  cloud-init secret is persisted for Windows VMs too.
- `getInitUserData` now returns a bare `#cloud-config\n` header for
  Windows instead of the Linux qemu-guest-agent runcmd template
  (which would fail on Cloudbase-Init). VMDP installs the QGA on
  Windows as a native service, so the runcmd path is not needed.

The "Install guest agent" checkbox stays disabled for Windows
because it specifically drives the Linux QGA-via-runcmd recipe.

Fixes point 2 of harvester/harvester#11124.

* fix(vm): do not clear cloud-config on isWindows watcher fire

The isWindows watcher runs on every change of the isWindows computed
property, including on mount when editing an existing Windows VM. Setting
this['userScript'] and this['networkScript'] to undefined at that point
wipes the cloud-config data that was just loaded from the existing VM's
cloudinit secret, so the Advanced -> Cloud Config editor shows empty
even though the VM has data on the wire.

Remove the two clears - Cloud Config is now supported for Windows guests
by this PR, so there is no reason to unset the user/network scripts when
the OS type is Windows. sshKey and installAgent remain gated (SSH keys
are injected via cloud-init on Linux only, and the qemu-guest-agent
package install checkbox does not apply to Windows).

* refactor(vm): Get CloudInit working for VM templates

- Remove unnecessary osType watcher in cloud config. The watcher (see `pkg/harvester/edit/kubevirt.io.virtualmachine/VirtualMachineCloudConfig/DataTemplate.vue`) that cleared the cloud config template for Windows VMs is no longer necessary.
- Automatically strip the CloudInit `User Data` properties `package_update` and `packages` for OS type `Windows`.
