lfs: add a switch to `hg verify` to ignore the content of blobs
Trying to validate the fulltext of an external revision causes missing blobs to
be downloaded and cached. Since the downloads aren't batch prefetched[1] and
aren't compressed, this can be expensive both in terms of time and space.
I made this a tri-state instead of a simple bool because there's an existing
(undocumented) config to handle this, and it would be weird if `hg verify` were
to suddenly start ignoring that config but an `hg recover` initiated verify
honors it. Since this uses the same config setting, it too will skip
rename verification (which requires fulltext, but not for LFS).
