Replace key_exchange_info with key_exchange_group.

Narrow to key_exchange_group in net::SSLInfo. The one place where
key_exchange_info remains is serialization code which sadly must filter
out garbage values.

This removes the DHE group size histogram which was the last consumer of
the non-ECDHE values. With DHE behind a fallback and now removed, there
is no need for this histogram.

rsleevi: This look good? I think you had opinions on how we resolve this on the
earlier CL. (I don't care strongly as to whether we burn a new flag or try to
map key_exchange_info. I went with the latter here.)

Replace key_exchange_info with key_exchange_group.

out garbage values.

This removes the DHE group size histogram which was the last consumer of
