Enable Curve25519 in host and client for PIN-based and third-party auth.

Enable Curve25519 in host and client for PIN-based and third-party auth.

Now client and host can use Spake2Authenticator instead of
V2Authenticator for both PIN-based auth and third-party auth. The plan
is to use cleanup It2Me to use hashed ID, so it will be possible to
remove spake2_plain method completely, so I'm not adding Curve25519
version.
Also pairing authentication needs move work to enable Curve25519 (see
crbug.com/593123), so it's going to be done separately.

Spake2Authenticor implements SPAKE2 over Curve25519, which is defined
in https://tools.ietf.org/html/draft-irtf-cfrg-spake2-03 .

LGTM, but please update the CL description with a brief overview of Curve25519
and perhaps a link to an RFC or similar.
