cmd/go: implement -reuse for Mercurial repos

Browse source 
When we added -reuse in CL 411398, we only handled Git repos.
This was partly because we were focused on Git traffic,
partly because Git is the dominant module VCS, and
partly because I couldn't see how to retrieve the metadata needed
in other version control systems.

This CL adds -reuse support for Mercurial, the second
most popular VCS for modules, now that I see how to
implement it. Although the Mercurial command line does
not have sufficient information, the Mercurial Python API does,
so we ship and invoke a Mercurial extension written in Python
that can compute a hash of the remote repo without downloading
it entirely, as well as resolve a remote name to a hash or check
the continued existence of a hash. Then we can avoid
downloading the repo at all if it hasn't changed since the last check
or if the specific reference we need still resolves or exists.

Fixes #75119.

# Mercurial extension to add a 'goreposum' command that
# computes a hash of a remote repo's tag state.
# Tag definitions can come from the .hgtags file stored in
# any head of any branch, and the server protocol does not
# expose the tags directly. However, the protocol does expose
# the hashes of all the branch heads, so we can use a hash of
# all those branch names and heads as a conservative snapshot
# of the entire remote repo state, and use that as the tag sum.
# Any change on the server then invalidates the tag sum,
# even if it didn't have anything to do with tags, but at least
# we will avoid re-cloning a server when there have been no
# changes at all.
#
# Separately, this extension also adds a 'golookup' command that
# returns the hash of a specific reference, like 'default' or a tag.
# And golookup of a hash confirms that it still exists on the server.
# We can use that to revalidate that specific versions still exist and
# have the same meaning they did the last time we checked.
#
# Usage:
#
# hg --config "extensions.goreposum=$GOROOT/lib/hg/goreposum.py" goreposum REPOURL
