Migrate to AeadInOut

[baloo]

Replaces the previous AeadInPlaceDetached impls with AeadInOut, which was introduced in RustCrypto/traits#1793

Depends:

• deoxys: rewrite the internals to use inout #666
• ocb3: migrate internals to use inout #667
• ascon-aead: rewrite internals to use inout #673
• aead: adds a dev::MockBuffer to smoke test AEADs implementation traits#1797

I would wait with this migration a bit. I plan to open several PRs to change aead APIs further and we probably will need to discuss them a fair amount.

I don't mind waiting to merge but I'll get this branch to a point where it can be used in a [patch.crates-io] by a consumer which is not currently the case with master.

It would definitely be nice to get things in sync with master if we can. There are people who are trying to track these repos as git dependencies and that becomes difficult when they go out-of-sync. Ideally we'd have a PR to update the downstream repos ready to go before we merge changes in traits, which is my bad

[baloo]

I'll need to sort out the lack of MockBuffer for ascon and deoxys: RustCrypto/traits#1802 (comment)

[baloo]

last bit is ascon-aead and are located in #673 but that got closed.

[tarcieri]

@baloo can you update/recreate #673 so we can get this merged?

#687

This gets included here.

I think this is the last PR needed to reunite the workspace in formats.
