locking/atomic: scripts: factor out order template generation
Currently gen_proto_order_variants() hard codes the path for the templates used for order fallbacks. Factor this out into a helper so that it can be reused elsewhere. This results in no change to the generated headers, so there should be no functional change as a result of this patch.
