Change xml processor names in script processor to match convention (#…

…26263) (#26282)

In the script processor, the `decode_xml` and `decode_xml_wineventlog` processors are now available as `DecodeXML` and `DecodeXMLWineventlog` respectively. This follows the same naming conventions as other processors exposed though the `script` processor. For example you can write `new processor.DecodeXML({...})`.
