Benjamin Valentin 39951a948e net/netif: move gnrc_netif_addr_to/from_str() to netif
These functions are independent from GNRC and can be used by stack-agnistoc
code.
Avoid pulling in a GNRC dependency by moving those two helper functions to
`netif`.

The old function names are kept as `static inline` wrapper functions to avoid
breaking API users.
