This PR builds on the https://github.com/llvm/llvm-project/pull/158314 and adds the lowering support for `-gdwarf-N` flag. The changes to pass the information to `AddDebugInfo` pass are mostly mechanical. The `AddDebugInfo` pass adds `ModuleFlagsOp` in the module which gets translated to correct llvm metadata during mlir->llvmir translation. There is minor correction where the version is set to 0 in case no -debug-version flag is provided. Previously it was set to 2 in this case due to misreading of clang code.
