lfs: add a fileset for detecting lfs files

This currently has the same limitation as {lfs_files}, namely it doesn't report
removed files.

We may want a dedicated 'lfs()' revset for efficiency, but combining this with
the 'contains()' revset should be equivalent for now.  Combining with
'set:added()' or 'set:modified()' inside 'files()' should be equivalent to a
hypothetical lfs_adds() and lfs_modifies().  I wonder if there's a way to tweak
the filesets to evaluate lazily, to close the efficiency gap.

It would also be interesting to come up with a template filter for '{files}'
that looked at the pattern to 'files()', and filtered appropriately.  While
passing a fileset as the pattern to `hg log` does filter '{files}', the set is
evaluated against the working directory, so there's no way to list all non-lfs
files above a certain size in all revisions, for example.
