Adds ACVP test coverage for deterministic ECDSA based on the NIST spec:
https://pages.nist.gov/ACVP/draft-fussell-acvp-ecdsa.html
Notably there is no corresponding acvp_test.config.json update in this
commit because ACVP DetECDSA only specifies sigGen mode.
The ACVP ECDSA sigGen tests are not amenable to testing against
static data because the test vectors don't provide a key pair to use for
the signature, just the message. The module wrapper has to generate its
own keypair and return the public key components with the signature.
DetECDSA produces deterministic signatures only when signing the same
message with the same key.
