82c9b8b494 C++: Ensure only one Variable exists for every global variable 
Depending on the extraction order, before this change there might be multiple
`GlobalVariable`s per declared global variable. See the tests in
`cpp/ql/test/library-tests/variables/global`. This change ensures that only one
of those `GlobalVariable`s is visible to the user if we can locate a unique
definition. If not, the old situation persists.

Note that an exception needs to be made for templated variables. Here, the
definition refers to the non-instantiated template, while a declaration that
is not a definition refers to an instantiation. In case the instantiation refers
to a template parameter, the mangled names of the template and the instantiation
will be identical. This happens for example in the following case:
```
template <typename T>
T x = T(42);           // Uninstantiated templated variable

template <typename T>
class C {
  T y = x<T>;          // Instantiation using a template parameter
};
```
Since the uninstantiated template and the instantiation are two different
entities, we do not unify them as described above.

880c785efe C++: Ensure we can round trip between (forward) class declarations 
This was already possible when the forward class declaration and the class
definition occurred in the same scope. However, there is a common C++ usage
pattern in which this is not the case (when only a pointer to the class is
needed). In this latter scenario we could not round trip between the (forward)
`DeclarationEntry` and the `Declaration`.

Effectively this changes the code to:
```
if exists(TypeDeclarationEntry e | e.getType() = this)
then result.getType() = this
else ...
```
We use `type_decls` instead to stay close to the original code.
