pki_crypto: Use EVP_DigestSign* and EVP_DigestVerify*

Browse Source 
Use the newer APIs EVP_DigestSign{Init}() and EVP_DigestVerify{Init}()
to generate and verify signatures instead of the older EVP_Sign{Init,
Update, Final} and EVP_Verify{Init, Update, Final} if supported.

Also use the single shot signature/verification if supported as all the
input is provided at once.

This is a preparation to use Ed25519 implementation from OpenSSL.
