Generate the "New types/enums/etc" sections of the OpenCL Extensions appendix

Following the initial step towards a unified OpenCL specification that describes core features and extensions, a new appendix giving an overview of all the extensions included in the specification was added (currently Appendix I). For each individual extension, a list of the new enums, features, structures, etc is given. These lists are currently authored manually, which is error prone and does not enable large-scale changes to how the information is presented. These sections should be generated automatically from the XML specification.

Start by examining the manually authored “New types/enums/etc” sections in Appendix I and the XML specification that provides their source data. Identify the existing documentation-generation entry point, then verify that these sections are generated automatically and that the output covers each extension’s enums, features, structures, and other listed items.
