fix(tools/mg): Support applying args to mg run (empty-target) r/5329
With this, we can disambiguate the following `mg run` invocations: ```shell $ mg run :foo # run the virtual target, foo, with no args $ mg run -- :foo # run the empty target and pass the arg, :foo, to it ``` Change-Id: Id6395b36a4d8ef3f325937e322e1c27b8630b556 Reviewed-on: https://cl.tvl.fyi/c/depot/+/7408 Tested-by: BuildkiteCI Reviewed-by: tazjin <tazjin@tvl.su> Reviewed-by: sterni <sternenseemann@systemli.org>
