read_loose_refs(): read refs using resolve_ref_recursively()

There is no need to call read_ref_full() or resolve_gitlink_ref() from
read_loose_refs(), because we already have a ref_store object in hand.
So we can call resolve_ref_recursively() ourselves. Happily, this
unifies the code for the submodule vs. non-submodule cases.

This requires resolve_ref_recursively() to be exposed to the refs
subsystem, though not to non-refs code.
