AK: Add a Stream::write_until_depleted overload for string types

Browse Source 
All string types currently have to invoke this function as:

    stream.write_until_depleted("foo"sv.bytes());

This isn't very ergonomic, but more importantly, this overload will
allow String/ByteString instances to be written in this manner once
e.g. `ByteString::view() &&` is deleted.
