exchange: improve computation of relevant markers for large repos
Find the candidates for nodes with relevant markers by going over
all markers instead of iterating over all nodes. Most nodes will
not have markers anyway.
Further optimize the code by allowing revsets as well, which reduces the
materialization cost.
