 Improve performance of `bp_sort_by_key()`.

 `bp_sort_by_key()` originally used `create_function()` to allow sorting by
 dynamic `$type` and `$key`. However, `create_function()` has a tendency to
 perform poorly. PHP 5.3 anonymous closures are much faster, but are
 unavailable
 as long as we support PHP 5.2. So we introduce a new class that plays a
 role
 similar to an anonymous closure, with a similar speed benefit.

 Fixes #6864.
