branchcache: add more test for the logic around obsolescence and branch heads

While working on branch-cache-v3, we noticed some ambiguity in the
filtered+obsolete hash. However this was only caught by a rebase test by
chance.

It seems important to explicitly tests these cases.

# Dummy extension to define a namespace containing revision names


from mercurial import namespaces


def reposetup(ui, repo):
    names = {b'r%d' % rev: repo[rev].node() for rev in repo}
    namemap = lambda r, name: names.get(name)
    nodemap = lambda r, node: [b'r%d' % repo[node].rev()]

    ns = namespaces.namespace(
        b'revnames',
        templatename=b'revname',
        logname=b'revname',
        listnames=lambda r: names.keys(),
        namemap=namemap,
        nodemap=nodemap,
    )
    repo.names.addnamespace(ns)
