clean/smudge: allow clean filters to process extremely large files
The filter system allows for alterations to file contents when they're moved between the database and the worktree. We already made sure that it is possible for smudge filters to produce contents that are larger than `unsigned long` can represent (which matters on systems where `unsigned long` is narrower than `size_t`, most notably 64-bit Windows). Now we make sure that clean filters can _consume_ contents that are larger than that. Note that this commit only allows clean filters' _input_ to be larger than can be represented by `unsigned long`. This change makes only a very minute dent into the much larger project to teach Git to use `size_t` instead of `unsigned long` wherever appropriate.
