[WTF] Integrate simdutf
https://bugs.webkit.org/show_bug.cgi?id=250112
rdar://104145576
Reviewed by Michael Saboff.
Add simdutf for faster base64 processing for new Base64 features in ECMAScript.
Once it implements replacement character handling, we can also consider using
it for
UTF-8 / UTF-16 conversion too. Apple OSS Approval: OSS-13396
