[index] Update indexing to handle CXXDeductionGuideDecls properly
CXXDeductionGuideDecls can't be referenced so there's no need to output a symbol occurrence for them.
Also handle DeducedTemplateSpecializationTypeLocs in the TypeIndexer so we don't miss the symbol occurrences of the corresponding template decls.
