[PATCH 3/3] string_list: Remove string_list_insert_at_index from its API

[Stefan Beller <sbeller@google.com>]

This function behaves the same as string_list_insert, just the
starting indexes for searching, where to insert into the list is also
a parameter. So if you have knowledge on where to search for the string
to be inserted, you may have a speed up version of string_list_insert.

As we're not using this function throughout the codebase, get rid of it.
