Add experimental handshake hints API.

See go/handshake-hints (internal).

CL originally by Bin Wu <wub@google.com>. I just reworked the tests and
tidied it up a bit. This is the start of a replacement for the split
handshakes API. For now, only TLS 1.3 is supported. It starts with an
initial set of hints, but we can add more later. (In particular, we
should probably apply the remote handshaker's extension order to avoid
needing to capability protect such changes.)
