path: expand internal path selection API to allow for additional types

Currently, nothing new is actually implemented but the idea is simply to
just pass a type string all the way up from mp_find_user_file down to
actually getting the platform path. This allows for selecting different
directories besides the user's native config directory. See the next
commit for an implementation.
