Make SQLLiteCodeFirst FIPS compliant

This PR makes SQLiteCodeFirst FIPS compliant, needed to operate on US federal or many state government systems as it is a requirement for software vendors, replacing the SHA512Managed class with the SHA512CryptoServiceProvider.

What is FIPS compliance? FIPS stands for Federal Information Processing Standards and are US Government standards that provide a benchmark for implementing cryptographic software

SHA512CryptoServiceProvider uses the FIPS 140-2 validated (FIPS = Federal Information Processing Standards) Crypto Service Provider (CSP) while SHA256Managed does not.
