slontis f3090fc710 Implement deterministic ECDSA sign (RFC6979)
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.
