[WTF] Remove UUID version of ObjectIdentifier
https://bugs.webkit.org/show_bug.cgi?id=322324 rdar://185566036 Reviewed by Ben Nham. I introduced this version of ObjectIdentifier two years ago, when I was more naïve and less pragmatic. Remove this unnecessary and unused version by effectively reverting 279402@main. This greatly re-simplifies the code and also makes crash log stack symbols and compilation errors a lot easier to read.
