Support for PQC algorithms: ML-KEM, ML-DSA and SLH-DSA ?

A few days ago NIST standardized 3 PQC, algorithms:
NIST 203: ML-KEM (Module-Lattice-Based Key-Encapsulation Mechanism Standard, based on: Crystals Kyber)
NIST 204: ML-DSA (Module-Lattice-Based Digital Signature Standard, based on: Crystals Dilithium)
NIST 205: SLH-DSA (Stateless Hash-Based Digital Signature Standard, based on: SPHINCS+)

For the announcement see:
https://cloudsecurityalliance.org/blog/2024/08/15/nist-fips-203-204-and-205-finalized-an-important-step-towards-a-quantum-safe-future

It would be nice if these were added to webcrypto as well.

Various implementations (commercial and opensource) already exist as the candidate algorithms have been field tested for quite some time.
E.g.

• https://github.com/pq-crystals/dilithium
• https://github.com/randombit/botan

Chromium already supports Kyber for TLS key exchange since August 2023: https://www.thesslstore.com/blog/google-chrome-adds-support-for-a-hybrid-post-quantum-cryptographic-algorithm/

Start by reviewing the Web Cryptography API context and the NIST FIPS 203, 204, and 205 announcements linked in the issue. Compare the existing WebCrypto scope with the cited implementations from pq-crystals and Botan. Done would require a defined proposal and agreed support for ML-KEM, ML-DSA, and SLH-DSA, but the issue names no files or tests.
