Ability to remove the "Preview" popup

[trovster]

I haven't configured any showOnPreview() fields, so all my resources have no information in the "Preview" popup. There should be a way to disable this button. Either it counts if there are any preview fields – no fields, button isn't shown – or it can be disabled using policies.

Looking through the code, you can disable this button if you disable the ability to view a resource. I don't want to disable this completely, only the preview.

<DropdownMenuItem
  v-if="resource.authorizedToView"
  :data-testid="`${resource.id.value}-preview-button`"
  :dusk="`${resource.id.value}-preview-button`"
  as="button"
  @click.prevent="openPreviewModal"
  :title="__('Preview')"
>
  {{ __('Preview') }}
</DropdownMenuItem>

There should be a policy method called preview() which can be configured to disable this button. This new method could default to the view() method if not present. This is like the replicate functionality, which defaults to using the update() check if the specific replicate() method doesn't exist.
