[clang] Fix sorting module headers (#73146)
Struct Module::Header is not a POD type. As such, qsort() and
llvm::array_pod_sort() must not be used to sort it. This became an issue
with the new implementation of qsort() in glibc 2.39 that is not
guaranteed to be a stable sort, causing Headers to be re-ordered and
corrupted.
Replace the usage of llvm::array_pod_sort() with std::stable_sort() in
order to fix this issue. The signature of compareModuleHeaders() has to
be modified.
Fixes #73145.
