Microvias on non-visible layers are partially rendered

Description

Thanks to #13566 (closed) µVias now have numbers which show from which layer to which layer they go.

altium_vias.PcbDoc

Altium:

Kicad:

Steps to reproduce

1. open pcbnew in standalone mode
2. import altium_vias.PcbDoc

In Altium it's possible to only show the vias connected to a certain layer.

For Example those connected to Top:

If I try the same in Kicad by selecting Preset "Front Layers" I get this view:

Via 5-8 / 6-8 / 7-8 are half visible, but you no longer can select them.

So I propose to remove this none selectable graphic shape as well, when the via is not visible on the selected layer.
