QDoc: Move `sortName` out of `Section`

`Section::sortName` is an internal method that is used to generate
sortable identifiers for `Node`s that are partitioned by a `Section`.

The method is currently private under `Section` but does not use any
internal state of `Section`, simply requiring any `Node` input.

Hence, the method was removed from `Section`'s interface in favor of
being a free-function visible only in the implementation file.
