[mertcanaltin]

I used stringView in simdutf for large strings, small strings continue as they are

The benchmark result for buffers is very long, so I created a gist for this benchmark result
all results:

Be aware that when doing many comparisons the risk of a false-positive result increases.
In this case, there are 471 comparisons, you can thus expect the following amount of false-positive results:
  23.55 false positives, when considering a   5% risk acceptance (*, **, ***),
  4.71 false positives, when considering a   1% risk acceptance (**, ***),
  0.47 false positives, when considering a 0.1% risk acceptance (***)

The benchmarks show mostly regressions, no?

I only changed the UTF-8 calculation for Buffer.byteLength(). The regression results you see may be due to the local environment. Could you run benchmark-ci for me? That way we can be more certain.

Thanks for the review @BridgeAR Pushed a fix for the regressions and updated results

issue was String::ValueView overhead eating simdutf gains on one-byte strings. Now I grab external one-byte pointers directly (zero-copy), skip simdutf for small one-byte strings (≤1024) using V8's native path, and apply full simdutf for two-byte strings after 128 bytes.

Results:

@BridgeAR can you rereview? the benchmarks seems to be unstable enough to show differences in untriggered paths
