[crypto] Support SHA-{224,384,512} in X.509 certificates 

Add support for SHA-224, SHA-384, and SHA-512 as digest algorithms in
X.509 certificates, and allow the choice of public-key, cipher, and
digest algorithms to be configured at build time via config/crypto.h.

Originally-implemented-by: Tufan Karadere <tufank@gmail.com>
