Refactor CppElementEvaluator

Browse Source 
Separate the use of CppElementEvaluator for CppHoverHandler from
the use for CppTypeHierarchyWidget. They are in fact much
different things.

Fix CppHoverHandler (enabled when ClangCodeModel plugin is disabled)
showing tooltips for symbols other than class or template.
Fix CppHoverHandler showing full template arguments for typedefs.
