Store bootstrap_llvm_target and use it to set LlvmTarget in bindists
This mirrors some existing logic for the bootstrap_target which influences how TargetPlatform is set. As described on #21970 not storing this led to `LlvmTarget` being set incorrectly and hence the wrong `--target` flag being passed to the C compiler. Towards #21970
