This is a rather large change because it touches public APIs, so I want to include all possible changes to make it easier for our current users to migrate in one go.

Notable changes:
* Add a mechanism that allows to restrict the visibility of functions that accept cleartext keys.
* s/Aead/AEAD/, s/Mac/MAC/, s/ComputeMac/ComputeMAC/, s/VerifyMac/VerifyMAC/, s/PublicKeySign/Signer/, s/PublicKeyVerify/Verifier/
* s/aead.GetPrimitive/aead.New/, etc.
* s/aead.RegisterStandardKeyTypes/aead.Register/, etc.

As a result of this, github.com/google/tink/go/tink/tink becomes
github.com/google/tink/go/tink.

To re-generate BUILD files, run bazel run :gazelle.

These archives are prepared on-the-fly by GitHub and are not
guaranteed to be the same every time (for example, the order of files
within the archive could change).

We also need a new version of rules_go because the version that
we were using also depends on GitHub archives. This explains
the changes in go/.

Also switch to googletest's provided bazel BUILD file, as
recommended by the googletest team.
