util: move validations for text decoder to c++

[anonrig]

This is the 3rd pull request for my text-decoder performance patches. It removes any unnecessary check and moves them to the C++ side. I'll update the description when benchmark CI is complete.

In this case, there are 54 comparisons, you can thus expect the following amount of false-positive results: 2.70 false positives, when considering a 5% risk acceptance (*, **, ***), 0.54 false positives, when considering a 1% risk acceptance (**, ***), 0.05 false positives, when considering a 0.1% risk acceptance (***)

Just a heads up, while I personally really like this change and think it’s a good idea, this isn’t really in line with what the project has been doing in the past years in terms of input validation (which is to validate in JS and add CHECKs in C++).
