Macedonian (MK) layout

Created by: boriseto

I've created the layouts without testing, since I've just installed the UBports on my device and I'm with limited connectivity where I am located at the moment due to government restrictions because of the virus situation. Anyway, the layout should be okay the way it is committed since it's the most popular one used in other platforms as well. Since it's based on the Serbian one (just edited the needed keys), it should be okay.
