When using attributes by plugins (both in clang and clang-tidy) the preprocessor functions `__has_attribute`, `__has_c_attribute`, `__has_cpp_attribute` still returned 0. That problem is fixed by having the "hasAttribute" function also check if any of the plugins provide that attribute. This also adds C2x spelling to the example plugin for attributes so that `__has_c_attribute` can be tested. Differential Revision: https://reviews.llvm.org/D144405
