CppTools: Add CppToolsBridge

We broke the dependency of
BaseEditorDocumentProcessor *BaseEditorDocumentProcessor::get(const QString &filePath)

It's hiding static calls and it is much easier to do it that way than to
provide a reference to every user. It's also possible to exchange it with
different implementations for different test cases.
