feat: align the storage performance options with the Rancher machine pool form (#1212)

* feat: align the storage performance options with the Rancher machine pool form

Show the storage performance profile on every volume instead of behind a
collapsible toggle, and move the VM-wide options to a plain Storage
Performance section in the Advanced Options tab. Put the Native I/O tip in
a live region so screen readers announce the cache mode change, use an
integer input for the I/O thread count, and use the same copy as the
Rancher form.

Skip the view-only backup row in the image and container volumes when it
has nothing to show, so it no longer adds an empty gap above the profile.

* fix: announce the storage performance warnings and name the virtio requirement

- Put the bus tip and the Filesystem warning in an always-rendered status
  region. They appear above the field being changed, so screen readers need
  them announced.
- Say in the bus tip that a dedicated I/O thread needs the virtio bus, because
  KubeVirt rejects it on any other bus.
- Mark I/O Thread Count as required while editing, like the Rancher form.

* fix: state only the dedicated I/O thread requirement in the bus tip

Neither the Harvester docs nor KubeVirt tie cache mode or I/O mode to the bus,
so stop saying that those options work best on virtio.
