Revert "C++: add support for resolving typedefs for template arguments"

This reverts commit c228b36c.

There are multiple issues with the reverted patch:
  * Infinite loop due to indirect recursion e.g. when opening projectmodels.cpp
  * Crash when executing CppTools tests on Windows (no infinite loop)
