  Build fails with libxml2 version 2.12.0 due to API change
https://bugs.webkit.org/show_bug.cgi?id=265128

Reviewed by Philippe Normand.

Starting with libxml2 2.12.0, the API has changed the const-ness of the
xmlError pointers, which results in a build error due to a mismatched
type in the parsing error callback. This papers over the difference by
using preprocessor conditionals.

* Source/WebCore/xml/XSLTProcessor.h: Use const when building against
  libxml2 2.12.0 or newer.
* Source/WebCore/xml/XSLTProcessorLibxslt.cpp:
(WebCore::XSLTProcessor::parseErrorFunc): Ditto.
