both of them are the same exact thing developed and maintained by pretty much same exact people (see contributors). the difference is that it is worked on under bitcoin-core github account and in a separate repository and the stable versions are pulled to bitcoin account in bitcoin/bitcoin repository.
the benefit is that if a developer wanted to use libsecp256k1 in their project they don't have to download the much bigger project (bitcoin core) and extract the libsecp256k1 from it. they can easily download a standalone repository and compile that without having to remove the extra parts (bitcoin core related parts).

There are two secp256k1 implementations that are related to Bitcoin-Core:
https://github.com/bitcoin-core/secp256k1
https://github.com/bitcoin/bitcoin/tree/master/src/secp256k1
What is the more authoritative implementation? What secp256k1 library should be used?
It seems like https://github.com/bitcoin/bitcoin/tree/master/src/secp256k1 is a subtree of the standalone bitcoin-core/secp256k1 repo. I would use bitcoin-core/secp256k1, it looks like libbtcoin forked it and it looks more up to date than the official bitcoin repo.https://github.com/bitcoin-core/secp256k1
https://github.com/bitcoin/bitcoin/tree/master/src/secp256k1
What is the more authoritative implementation? What secp256k1 library should be used?
If you want to check for yourself, just look through this recent commit log
https://github.com/bitcoin/bitcoin/commit/8903a1a0a78a705402123d2a5c465217cb9d791c
and compare the files to bitcoin-core/secp256k1, you'll see it's the same.
