This PR is based off the contributions in PR #9223 by Jemmy1228. It has been modified and reworked to: (1) Work with providers (2) Support ECDSA and DSA (3) Add a KDF HMAC_DRBG implementation that shares code with the RAND HMAC_DRBG. A nonce_type is passed around inside the Signing API's, in order to support any future deterministic algorithms.
