AK/Userland: Use AK/Endian.h for portable byte swapping in ntpquery

Browse source 
Create macros for the byte swap operations one would expect to be in
endian.h or byteswap.h in AK/Endian.h. It's likely a similar/different
change will be needed for BSDs, but there's no github action for those
added to the project yet.
