  Normalize Latin-1 characters in `String#normalize("NFKC")``

Reviewed by Alexey Proskuryakov.

The `String.prototype.normalize` implementation has a fast-path in
cases where normalization does not affect the string. It was incorrectly
assumed that NFKC does not affect 8-bit strings. The only normalization
that doesn't affect them is NFC.
