TinyCrypt SSL: Extend scope use of TC in CliKeyExchange writing
Extend scope of TC in ECDH-param extraction from CRT
Previously, TinyCrypt was only used for ECDHE-ECDSA/RSA ciphersuites.
This commit is a step towards using it for _all_ ciphersuites involving
ECDHE (specifically: ECDHE, ECDHE-PSK, static ECDH), extending the scope
of the use of TinyCrypt in the writing of the ClientKeyExchange message.
