Export the preload_index() function

Browse Source 
The purpose of this function is to stat() the files listed in the index
in a multi-threaded fashion. It is called directly after reading the
index in the read_index_preloaded() function.

However, in some cases we may want to separate the index reading from
the preloading step, e.g. in builtin/add.c, where we need to load the
index before we parse the pathspecs (which needs to error out if one of
the pathspecs refers to a path within a submodule, for which the index
must have been read already), and only then will we want to preload,
possibly limited by the just-parsed pathspecs.

So let's just export that function to allow calling it separately.
