Expose template types in libclang

[OlivierJG]

Summary

The various template types are currently given as CXType_Unexposed, where exposing them would be very useful for knowing when you can call functions that work on them, such as clang_Type_getNumTemplateArguments/clang_Type_getTemplateArgumentAsType.
