BN_gcd function

@RecordUse.new() @Native<Int Function(Pointer<BIGNUM>, Pointer<BIGNUM>, Pointer<BIGNUM>, Pointer<BN_CTX>)>(ffi.Pointer<BIGNUM>, ffi.Pointer<BIGNUM>, ffi.Pointer<BIGNUM>, ffi.Pointer<BN_CTX>)>(symbol: 'bssl_dart_BN_gcd') int BN_gcd(Pointer<BIGNUM> r, Pointer<BIGNUM> a, Pointer<BIGNUM> b, Pointer<BN_CTX> ctx,)

BN_gcd sets r = gcd(a, b). It returns one on success and zero otherwise.
