[C++] Store class template name without its template arguments

Browse Source 
Summary:
Don't store redundant information in C++ template Type.Name.t.

New signature:
```
| CppClass (qual_name, template_args)
```

For example, for `std::shared_ptr<int>`, will look like this:
```
| CppClass (["std", "shared_ptr"], Template [int])
```
While it used to be:
```
| CppClass (["std", "shared_ptr<int>"], Template (["std", "shared_ptr"], [int]))
```
