a3f4d1bf66 Move contextual queries from src to lib 
With this change, users are now able to run View AST command in
vscode within vscode workspaces that do not include the core libraries.
The relevant core library only needs to be installed in the package
cache.

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.
