AK: Rename the const overload of FixedMemoryStream::bytes()

Browse source 
Due to overload resolutions rules, this simple code provokes a crash:

ReadonlyBytes readonly_bytes{};
FixedMemoryStream stream{readonly_bytes};
ReadonlyBytes give_them_back{stream.bytes()};
    // -> Panics on VERIFY(m_writing_enabled);
    // but this is fine:
auto bytes = static_cast<FixedMemoryStream const&>(*stream).bytes()

If we need to be explicit about it, let's rename the overload instead of
adding that `static_cast`.
