src: use simdutf for one-byte string UTF-8 write in stringBytes

[mertcanaltin]

I use simdutf::convert_latin1_to_utf8_safe for one-byte strings in StringBytes::Write UTF-8 path instead of V8's
WriteUtf8V2.

buffer.write(str, 'utf8') 577% faster

Be aware that when doing many comparisons the risk of a false-positive result increases.
In this case, there are 50 comparisons, you can thus expect the following amount of false-positive results:
  2.50 false positives, when considering a   5% risk acceptance (*, **, ***),
  0.50 false positives, when considering a   1% risk acceptance (**, ***),
  0.05 false positives, when considering a 0.1% risk acceptance (***)
