This reverts commit 1b589f4d4db27e3fcd81fdc5abeb9407753ab790 and relands the D89463 with the fix: update `MappingTraits<FileFilter>::validate()` in ClangTidyOptions.cpp to match the new signature (change the return type to "std::string" from "StringRef"). Original commit message: This: Changes the return type of MappingTraits<T>>::validate to std::string instead of StringRef. It allows to create more complex error messages. It introduces std::vector<std::pair<StringRef, bool>> getEntries(): a new virtual method of Section, which is the base class for all sections. It returns names of special section specific keys (e.g. "Entries") and flags that says if them exist in a YAML. The code in validate() uses this list of entries descriptions to generalize validation. This approach was discussed in the D89039 thread. Differential revision: https://reviews.llvm.org/D89463
