I have noticed it does not take long for solar panels in Kuwait to be coated in layers of dust. Does this reduce efficiency by any measurable amount?

Yes, the loss is quite significant, and of course dependent on how much dust has accumulated. The effect is worse in countries near the equator, as the panels are installed with a lesser tilt. 70% losses have been reported in some studies.

Yes, the effect is significant. But there are robots specifically designed for frequent, water-free cleanings in dusty regions:
