Reducing the number of comparisons and allocations when using validateObject.

Be aware that when doing many comparisons the risk of a false-positive
result increases. In this case, there are 4 comparisons, you can thus
expect the following amount of false-positive results:
  0.20 false positives, when considering a   5% risk acceptance (*, **, ***),
  0.04 false positives, when considering a   1% risk acceptance (**, ***),
  0.00 false positives, when considering a 0.1% risk acceptance (***)

I wonder if it wouldn't be better to just split it into 2 functions (one for default other with options) and if that would let us avoid the bit sorcery and still see the performance improvement.

@benjamingr Maybe, the bit sorcery still needed to not have a bunch of duplicated functions (one for each combination).

I can introduce internal functions but I don't think that will be worth adding one more hideStackFrames if I throw an exception.
It could be two functions, maybe validateObject and validateObjectWithOptions but this didn't look good to me, so I will keep it as is for now unless you have some suggestions.

According to #49928 (comment), this has little effect on the overall performance of Node.js. Still a good change to see.
