crypto/tls: don't cache marshal'd bytes
Only cache the wire representation for clientHelloMsg and serverHelloMsg during unmarshal, which are the only places we actually need to hold onto them. For everything else, remove the raw field. This appears to have zero performance impact: name old time/op new time/op delta CertCache/0-10 177µs ± 2% 189µs ±11% ~ (p=0.700 n=3+3) CertCache/1-10 184µs ± 3% 182µs ± 6% ~ (p=1.000 n=3+3)
