Pull request overview

This PR adds a new wolfCrypt implementation of Argon2 (RFC 9106) supporting Argon2d/Argon2i/Argon2id (v1.3 / 0x13), including an optional threaded slice-filling mode, plus build-system integration and test/benchmark coverage.

Changes:

• Introduces the Argon2 public API (wc_Argon2*) and implementation (wolfcrypt/src/argon2.c) with optional WOLFSSL_ARGON2_THREADS.
• Integrates Argon2 into Autotools/CMake/Zephyr builds, and ensures HAVE_BLAKE2B is implied when HAVE_ARGON2 is enabled to keep public headers buildable.
• Adds wolfCrypt test vectors + API unit tests and a benchmark entry for Argon2.
