Pull request description:
This replaces #23432 and part of #23561.
This PR introduces all of the ElligatorSwift-related changes (libsecp256k1 updates, generation, decoding, ECDH, tests, fuzzing, benchmarks) needed for BIP324.
ElligatorSwift is a special 64-byte encoding format for public keys introduced in libsecp256k1 in https://github.com/bitcoin-core/secp256k1/pull/1129. It has the property that *every* 64-byte array is a valid encoding for some public key, and every key has approximately $2^{256}$ encodings. Furthermore, it is possible to efficiently generate a uniformly random encoding for a given public key or private key. This is used for the key exchange phase in BIP324, to achieve a byte stream that is entirely pseudorandom, even before the shared encryption key is established.
