gh-99108: Replace SHA3 implementation HACL* version (#103597) 
Replaces our built-in SHA3 implementation with a verified one from the HACL* project.

This implementation is used when OpenSSL does not provide SHA3 or is not present.

3.11 shiped with a very slow tiny sha3 implementation to get off of the <=3.10 reference implementation that wound up having serious bugs. This brings us back to a reasonably performing built-in implementation consistent with what we've just replaced our other guaranteed available standard hash algorithms with: code from the HACL* project.

README.md

Algorithm implementations used by the hashlib module.

This code comes from the HACL* project.

HACL* is a cryptographic library that has been formally verified for memory safety, functional correctness, and secret independence.

Updating HACL*

Use the refresh.sh script in this directory to pull in a new upstream code version. The upstream git hash used for the most recent code pull is recorded in the script. Modify the script as needed to bring in more if changes are needed based on upstream code refactoring.

Never manually edit HACL* files. Always add transformation shell code to the refresh.sh script to perform any necessary edits. If there are serious code changes needed, work with the upstream repository.
