Ensure SDP records can be byte arrays/hex encoded

This addresses the issue on Bluez only. macOS ignore such
attribute values and WinRT implicitly converts them to hex strings.

The macOS debug stream operator produced slightly different output
compared to the other platforms. The output between the platforms
must match though. Therefore, the general version was copied over
to macOS.
