AST nodes using C++ Extractor (#1341)

* Extractor builds without any reference to syntax (as it will be helping to produce this!).

* Change macros to include the super class.

* WIP replacing defs files.

* Added indexOf(const UnownedSubString& in) to UnownedSubString.
Refactored extractor
* Output a macro for each type with the extracted info - can be used during injection in class
* Simplify the header file - as can get super type and last from macro now
* Store the 'origin' of a definition

* Some small tidy ups to the extractor.

* Improve comments on the extractor options.

* Made CPPExtractor own SourceOrigins

* Small fixes around SourceOrigin.

* Small tidy up around macroOrign

* WIP Visitor seems now to work correctly.
Split out types used by ast into slang-ast-support-types.h

* Fix remaining problems with C++ extractor being used with AST nodes.
Add CountOf to extractor type ids.
Added ReflectClassInfo::getInfo to turn an ASTNodeType into a ReflectClassInfo

* Fix compiling on linux.
Fix typo in memset.

* Small tidy up around comments/layout.
Moved NodeBase casting to NodeBase.

* Make premake generate project that builds with cpp-extractor for AST.

* Get the source directory from the filter in premake.

* Fix typo in source path

* Explicitly set the source path for  premake generation for AST.

* Special case handling of override to apease Clang.

* Use a more general way to find the slang-ast-reflect.h file to run the extractor.

* Appveyor is not triggering slang-cpp-extractor - try putting dependson together.

* Put building slang-cpp-extractor first.

* Disable some project options to stop MSBuild producing internal compiler errors.

* Try reordering the projects in premake5.lua

* Hack to try and make slang-cpp-extractor built on appveyor.

* Disable flags - not required for MSBuild on appveyor.

* Disable flags not required for build on AppVeyor.

* Updated Visual Studio projects with slang-cpp-extractor.

* Added Visual Studio slang-cpp-extractor project.
