Add BN support to the test infrastructure.
This includes support for: - comparisions between pairs of BIGNUMs - comparisions between BIGNUMs and zero - equality comparison between BIGNUMs and one - equality comparisons between BIGNUMs and constants - parity checks for BIGNUMs Reviewed-by: Rich Salz <rsalz@openssl.org> Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/3405)
