verify: also check full manifest validity during verify runs

Before this changes, `hg verify` only checked if a manifest revision existed and
referenced the proper files. However it never checked the manifest revision
content itself.

Mercurial is expecting manifest entries to be sorted and will crash otherwise.
Since `hg verify` did not attempted a full restoration of manifest entry, it
could ignore this kind of corruption.

This new check significantly increases the cost of a `hg verify` run. This
especially affects large repository not using `sparse-revlog`. For now, this is
hidden behind the `--full` experimental flag.
