fix: display "pause on layer"-button only when the macros exists

[meteyou]

Description

This PR fix the "Pause at Layer" button in the Status panel. Until now, you saw this button, if you don't have "Exclude objects" active, set Layer counts, but no macros (SET_PAUSE_AT_LAYER & SET_PAUSE_NEXT_LAYER).
