crypto/tls: enable TLS 1.3 and update tests

Browse source 
To disable TLS 1.3, simply remove VersionTLS13 from supportedVersions,
as tested by TestEscapeRoute, and amend documentation. To make it
opt-in, revert the change to (*Config).supportedVersions from this CL.

I did not have the heart to implement the early data skipping feature
when I realized that it did not offer a choice between two
abstraction-breaking options, but demanded them both (look for handshake
type in case of HelloRetryRequest, trial decryption otherwise). It's a
lot of complexity for an apparently small gain, but if anyone has strong
opinions about it let me know.

Note that in TLS 1.3 alerts are encrypted, so the close_notify peeking
to return (n > 0, io.EOF) from Read doesn't work. If we are lucky, those
servers that unexpectedly close connections after serving a single
request will have stopped (maybe thanks to H/2) before they got updated
to TLS 1.3.

Relatedly, session tickets are now provisioned on the client first Read
instead of at Handshake time, because they are, well, post-handshake
messages. If this proves to be a problem we might try to peek at them.

Doubled the tests that cover logic that's different in TLS 1.3.

The benchmarks for TLS 1.2 compared to be0f3c286b5 (before TLS 1.3 and
its refactors, after CL 142817 changed them to use real connections)
show little movement.

Comparing TLS 1.2 and TLS 1.3 at tip shows a slight (~5-10%) slowdown of
handshakes, which might be worth looking at next cycle, but the latency
improvements are expected to overshadow that.
