feat: Add SHA-512 and SHA-384 support to the SHA-256 VM extension

[Avaneesh-axiom]

Note to reviewer: the Github PR review UI doesn't diff some files properly across renaming despite my best efforts. For example, crates/circuits/sha256-air/src/air.rs -> crates/circuits/sha-air/src/air.rs isn't detected and it shows as deletion of the old file and creation of the new one. To make the review easier, consider reviewing each commit one at a time. The diffs work nicer that way.

Closes INT-3211 and INT-3213
