fs: add two type safe mapping helpers
Introduce i_{g,u}id_into_vfs{g,u}id(). They return vfs{g,u}id_t. This
makes it way harder to confused idmapped mount {g,u}ids with filesystem
{g,u}ids.
The two helpers will eventually replace the old non type safe
i_{g,u}id_into_mnt() helpers once we finished converting all places. Add
a comment noting that they will be removed in the future.
All new helpers are nops on non-idmapped mounts.
