bitbake: toastergui: Generic message for the layer details empty states

In the layer details page, change the message you see when
the number of targets or machines provided by a layer is
0, either because that's what's reported by a layer index
instance, or because Toaster does not have any information
about the layer.

The new message is more generic, in order to fit layers from
all layer sources.
