We can add them if we need them, but we're only using HKDF-SHA256 in
ECH. Keep the set small to encourage a common set of parameters.

This CL adds an initial implementation of the ECH server, with pieces of
the client in BoGo as necessary for testing. In particular, the server
supports ClientHelloInner compression with ech_outer_extensions. When
ECH decryption fails, it can send retry_configs back to the client.
This server passes the "ech-accept" and "ech-reject" test cases in
tls-interop-runner[0] when tested against both the cloudflare-go and nss
clients. For reproducibility, I started with the main branch at commit
707604c262d8bcf3e944ed1d5a675077304732ce and updated the endpoint's
script to pass the server's ECHConfig and private key to the boringssl
tool.
Follow-up CLs will update HPKE to the latest draft and catch us up to
draft-10.

AES_128_GCM is more common than AES_GCM_128 and matches the
specification.

In doing so, this switches make_errors.go to take library names as
parameters rather than detecting it from the CWD. (I considered
detecting it, but then we'd need to map evp -> crypto/whatever and
crypto/whatever -> evp in both directions.)
Since crypto/hpke currently sits in the EVP namespace, I've gone ahead
and added that, so it should be easier to define new errors in
crypto/hpke. I've not added crypto/cipher, etc., yet. Moving those will
be a breaking change (consumers that put ERR_LIB_CIPHER and ERR_LIB_EVP
in a switch/case need patches).
