perf build: Autodetect minimum required llvm-dev version
The new LLVM addr2line feature requires a minimum version of 13 to compile. Add a feature check for the version so that NO_LLVM=1 doesn't need to be explicitly added. Leave the existing llvm feature check intact because it's used by tools other than Perf.
This fixes the following compilation error when the llvm-dev version doesn't match:
util/llvm-c-helpers.cpp: In function 'char* llvm_name_for_code(dso*, const char*, u64)': util/llvm-c-helpers.cpp:178:21: error: 'std::remove_reference_t<llvm::DILineInfo>' {aka 'struct llvm::DILineInfo'} has no member named 'StartAddress' 178 | addr, res_or_err->StartAddress ? *res_or_err->StartAddress : 0);
