Nick Wellnhofer 09dac45ab9 fuzz: Add separate XInclude fuzzer
XIncludes involve XPath processing which can still lead to timeouts when
fuzzing. This will probably take a while to fix. The rest of the XML
parsing code should hopefully run without timeouts now. OSS-Fuzz only
shows a single timeout test case, so separate the XInclude from the core
XML fuzzer.
