Updated libsodium from 1.0.21 to 1.0.22.

Release notes

Sourced from libsodium's releases.

1.0.22

Version 1.0.22

This point release includes all the changes from 1.0.21-stable, plus:

• Post-quantum key encapsulation is now available. ML-KEM768, the
  NIST-standardized lattice-based KEM, is accessible through the
  crypto_kem_mlkem768_*() functions.
• X-Wing, a hybrid KEM combining ML-KEM768 with X25519 for protection
  against both classical and quantum adversaries, is available through the
  crypto_kem_*() functions. X-Wing is the recommended KEM for most
  applications.
• SHA-3 hash functions are now available as crypto_hash_sha3256_*()
  and crypto_hash_sha3512_*(), with both one-shot and streaming APIs.

Version 1.0.21-stable

• Performance: NEON optimizations for Argon2 on ARM platforms.
• Performance: SHA3 (Keccak1600) now leverages ARM SHA3 instructions when
  available on ARM platforms.
• Performance: WebAssembly SIMD implementations of Argon2 have been added.
• Emscripten: LTO is now disabled. With Emscripten 4, LTO produced
  WebAssembly modules with functions that ran significantly slower than
  without it.
• Emscripten: a new option allows compilation with SIMD support.
• Emscripten: native ESM module generation is now supported.
• JavaScript sumo builds now allow up to 80 MiB memory usage, so that
  crypto_pwhash with the interactive settings can be used in pure
  JavaScript, not just WebAssembly.
• XOF state alignment has been relaxed.
• crypto_core_keccak1600_state has been added.
• Export missing crypto_ipcrypt_nd_keygen() helper function.
• crypto_auth_hmacsha256_init and crypto_auth_hmacsha512_init now
  accept NULL key pointers (with a zero key length), for consistency with
  other _init functions.
• apple-xcframework: headers are now in a Clibsodium subdirectory
  to prevent module.modulemap collisions with other xcframeworks.
• Fixed compilation with GCC on aarch64 and gcc 4.x.
• On aarch64, aes256-gcm is now enabled even when not using clang,
  including MSVC.
• Added compatibility with Visual Studio 2026 when toolsets do not
  define PlatformToolsetVersion.
• Libsodium can be directly used as a dependency in a Zig project.
• Performance of MSVC builds has been improved.
