Subject: C++ extractor parsing slang.h (#2162)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Split doc extractor such that can be used in C++ extractor.

* Compiles. Update the stdlib docs.

* Fix issue on release builds.

* Add support for extracting documentation to C++ extractor.

* Dump out markup.
Make enum value backing type take tokens.

* Node::Type -> Node::Kind

* More improvements around Node::Type -> Node::Kind

* Support for parsing callable types.

* Fix issue params for callable, and default value for variable.

* Add support for static.

* Improve handling parsing of contained types.

* Small improvements around template consumption.

* Improve dumping with markup/static.

* Small improvements around reflection.

* Add more flexible handling of markers.
Allow reflection without markers.

* Handling external "C"
