Painter gizmos: reset out-of-range paint states at load (#16341)

Supports, seam, fuzzy skin and texture displacement loaded paint data with the default max_ebt, so a 3mf with a paint state above what the gizmo paints read past the 3-entry color table. Each gizmo now passes its highest paint state as max_ebt, as the MMU gizmo already does, and higher states load as unpainted.
