feat(Hyperv Desktop): Disable cloud-init for Hyperv Desktop images (LP: #2064280)

For Ubuntu 24.04 and later cloud-init is included in desktop images. This is not applicable for Hyperv images so
we can disable cloud-init. This leaves the cloud-init package installed but disabled so users can still
use it if they want.

This is a documented way to disable cloud-init. See https://cloudinit.readthedocs.io/en/latest/howto/disable_cloud_init.html
