In C, it is a common pattern to have `static inline` functions in headers to avoid ODR issues. Currently, when those headers are included in a GMF, the names are not found when two-phase name lookup and ADL is involved. Those names are removed by `Sema::AddOverloadCandidate`. Similarly, in C++, sometimes people use templates with internal linkage in headers. As the GMF was designed to be a transitional mechanism for headers, special case those functions in `Sema::AddOverloadCandidate`. This fixes <https://github.com/llvm/llvm-project/issues/98021>.
