[PM-15994] Move encryption to km ownership

[quexten]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/PM-15994

📔 Objective

Moves a lot of the remaining crypto domain from platform to km, since km will own the corresponding sdk code in the long term too. (Further, this also cleans up some internal km ownership and file structure in the process).

Specifically transferred:

• Encrypt service, (interface, implementations, and the service worker).
• Key Generation service
• EncString/similar
• SymmetricCryptoKey
• Cryptofunctionservice (interface, implementations)

seem to sometimes use relative imports. If you could please check them that would be appreciated.

Note: At this point the PR had to be updated to move dependencies to common/key-management/crypto instead of the key-management package to avoid dependency cycles.

@quexten due to the size of this PR, the Auth team has had issues with tooling to properly perform a review. Could you please see if you could reasonably break this up into multiple PRs for review? Perhaps a single service at a time?

I'll look into it. I believe in the first version of this PR it made sense to move all dependencies at once, since we were moving them to a separate package, leading to quite the mess of imports otherwise, but since it retargets the common library now, I think we can break it up.
