Adds ACVP test coverage for the SP 800-90A rev 1 ctrDRBG algorithm based on the NIST spec: https://pages.nist.gov/ACVP/draft-vassilev-acvp-drbg.html#section-7.2 The implementation in our FIPS module is a minimal implementation tailored to the specific needs of stdlib crypto. As a result we customize the ACVP capability registration so that: * predResistanceEnabled is false * only mode AES-256 is supported * for that mode, * derFuncEnabled is false * persoStringLen is 0 to disable personalization * additionalInputLen is 384 to match the [48]byte argument in our API Other capability values are chosen based on Table 4's ctrDRBG AES-256 w/o `derFuncEnabled` row: https://pages.nist.gov/ACVP/draft-vassilev-acvp-drbg.html#section-7.4 We do enable reseed in the capability, necessitating two acvptool commands: one that expects only 6 args and doesn't reseed ("ctrDRBG/AES-256"), and one that expects 8 args and does ("ctrDRBG-reseed/AES-256").
