Actually hide tabs with no visible fields

Description:

When there are no visible fields in a tab, hide the tab button from the tab bar

Detailed steps to reproduce the issue on a fresh Nova installation:

As per #6615 which is marked as done, but actually the tab button is currently only disabled, not hidden.

it's just a matter of replacing
:disabled="tab.visibleFieldsForPanel.visibleFieldsCount.value == 0"
with
v-show="tab.visibleFieldsForPanel.visibleFieldsCount.value > 0"
in components/Forms/TabsPanel

If you want to make this configurable it could be added via hideEmptyTabButtons() or a similar helper on the tab group?

The UX at the moment is strange as there are lots of buttons which are not clickable (and don't even look 'disabled').

@crynobone i really feel that just showing the tab buttons and not allowing them to be clicked (without even some visible 'disabled' state) is just confusing, and that the tabs should be hidden when there's no fields visible inside them - just as the fields themselves are hidden.
