[c++20][clangd] Simplify code using the new ConceptReference nodes.

Browse Source 
Directly traverse `ConceptReference`s in FindTarget.cpp.

There is no need for the extra logic for `AutoTypeLoc`s in SemanticHightlighting.cpp as the concept information is stored in a `ConceptReference` which is now traversed.
