graphlog: restore FILE glob expansion on Windows

graphlog: restore FILE glob expansion on Windows

On platforms not supporting shell expansion, scmutil.match() performs glob
expansion on 'pats' arguments. But _matchfiles() revset calls match.match()
directly, bypassing this behaviour. To avoid duplicating scmutil.match(), a
secondary scmutil.matchandpats() is introduced returning both the match object
and the expanded inputs. Note the expanded pats are also needed in the fast
path, and will be used by --follow code path.
