tags-fnode-cache: skip building a changectx in getfnode
Building a changectx object is costly, doing it just to retrieve the revision
number is suboptimal. Directly fetching the revision number from the changelog
provide a sizeable speedup to `hg debugupdatecache`.

# Many of the individual files that are excluded here confuse pytype

# conditionally. There's no good way to help it out with that as far as
# I can tell, so let's just hide those files from it for now. We should
# endeavor to empty this list out over time, as some of these are
