There is highway=stop and highway=give_way but their use is kind of
awkward. The wiki says to put it on a node before the intersection
which makes some sense but then anyone who actually wants to use it
has to do some calculation to figure out which direction of travel it
applies to. Which would mean finding the nearest intersection with a
similarly classed road to the tagged node. I typically only put
highway=stop on 4 way stops where it applies to all ways.
