feat: replace crypto md5 key/version hashing with single function based on xxhash

[h0tw1r3]

Continuation of PR #9397

This PR just adds a few commits to create a single function as requested (#9397 (comment)) and test coverage.

In addition to the performance improvements with xxhash, my motivation was to remove md5 crypto as a whole because it's not supported when enabling FIPS mode.

Original PR description below

---

Switch to using faster xxhash for cache keys and versions of data models instead of slow crypto.createHash('md5').
Use the fastest node xxhash implementation, written in ... of course rust :)

XXH3: generates 64 or 128-bit hashes, using vectorized arithmetic.

Here are some more info for those who is interested:
