cxx: Improved performance of CxxAstVisitor, CxxNameResolver and CxxName types

Browse Source 
* use unique_ptr for CxxName handling
* create CxxNameResolver from other
* improved string handling in CxxName types
* only traverse decls within projects
* use macro in ast visitor to call into each component instead of virtual calls
* improved CxxName caching performance
* refactored CxxNameResolver classes to use less locals
