AK: Migrate IPv6Address::to_deprecated_string() to ::to_string()

Browse source 
Change the name and return type of
`IPv6Address::to_deprecated_string()` to `IPv6Address::to_string()`
with return type `ErrorOr<String>`.

It will now propagate errors that occur when writing to the
StringBuilder.

There are two users of `to_deprecated_string()` that now use
`to_string()`:

1. `Formatted<IPv6Address>`: it now propagates errors.

2. `inet_ntop`: it now sets errno to ENOMEM and returns.
