Title:
  Hyperv desktop images no longer building in Noble

Status in livecd-rootfs package in Ubuntu:
  Fix Released
Status in livecd-rootfs source package in Noble:
  New

Bug description:
  We have not built Hyperv desktop images since Jammy and with the re-
  introduction of HyperV for Noble we have encountered build issues
  caused by refactoring and removals of code assumed to be redundant but
  the HyperV desktop images were actually using these code paths.

  In bbedffe6 we split the building of cloud images and non cloud to
  using an ddisk-image-uefi.binary and disk-image-uefi-non-cloud.binary
  respectively.

  In e38264ca there was a change which meant that any attempt to build
  hyperv images would result in incorrect disk size and incorrect disk
  label.

  A change in 76d79466 changed the logic of how the image size for amd64
  images were being set. This overrode the sizes set for the desktop
  images incorrectly.

  A change in 8fb21808 also removed many of the dependencies that the hyperv images require.
  This removal has been restored in this commit by adding them expliciltly in the hyperv hook.

  With Ubutnu 24.04+ cloud-init was introduced to desktop images. This
  is not required for HyperV images and can be disabled.

  This bug is to track the work to restore functioning Hyperv desktop
  image builds

  [ Impact ]

  Unable to build HyperV Desktop image.

  [ Test Plan ]

   * Successfully build image 
   * Launch through Windows HyperV manager successfully without any errors or warning. 

  [ Where problems could occur ]

   * If the image built does not launch in hyperv manager or has errors
  or warnings.

  [ Other Info ]

   * There is work required to migrate oem-config to the new
  provisioning stack but this is out of scope of this bug.
