Remove extras unused by OpenBao

[cipherboy]

These subpackages are unused by OpenBao. KMS is a package built on top
of go-kms-wrapping which uses a database to store encryption keys: this
is unnecessary in our case as we explicitly want all keys to be backed
by the underlying wrapper (which, admittedly in the case of cloud KMSes,
incurs some cost that extras/kms/ could avoid). Crypto adds, along other
things, a HMAC-SHA-256 implementation: if we find this useful, we could
add this directly to wrappers/ as an optional type (just like signing.go
is). Lastly, StructWrapping adds a way to encrypt arbitrary interfaces,
through a custom marshaling format built on protobuf.

extras/multi remains: it is unclear if it might potentially be useful
for multi-unseal in OpenBao in the future and aead/ had tests using it.

[cipherboy]

@JanMa It looks like I had to manually approve actions to run, since we were on a fork and GitHub wanted to make sure we understood them. :-D

We also seem to be building with different versions of protobuf than what the main repo uses; we should probably standardize on a single version of tooling across all repos. But that's probably for a future PR.

I was able to run:

$ make tidy-all dev check
... output elided ...

and have it past tests still.

@JanMa @DanGhita Any chance I could bother one of you for a review? The buf failure is unrelated and caused by using different versions of protobuf across our various projects.

Sorry for the delay, LGTM ✔️
