Remove %stringTypeHash and IsStringType() from CodeGeneratorV8.pm
Remove %stringTypeHash and IsStringType() from CodeGeneratorV8.pm

AtomicString isn't (shouldn't) used in IDL files, and thus it doesn't
make sense to have AtomicString in %stringTypeHash.
We should just replace IsStringType($type) with if($type eq "DOMString").
