Rename the TLS Supported Elliptic Curves extension to Supported Groups.

RFC 7919 renamed the Supported Elliptic Curves TLS extension to Supported
Groups and redefined it to include finite field DH (FFDH) in addition to
elliptic curve DH (ECDH). As such, rename the TLS extension and change the
associated code to refer to groups rather than curves.
