Convert ssl3_send_channel_id to CBB.

In doing so, simplify the mess around serializing the public key.
Channel ID specifies that you write x and y concatenated. Rather than
using the X9.62 serialization and chopping bits off, get the affine
coordinates and write them out in the same way we write r and s.

Also unify the P-256 sanity check around SSL_set1_tls_channel_id and
actually check the curve NID.
