run_binary should support custom mnemonic and progress message

A tiny FR for `run_binary`: Support passing a custom mnemonic and progress message (from rule attributes) to the binary action to increase feature parity w.r.t. `genrule`.

Start by locating the run_binary rule and compare how genrule handles mnemonic and progress message attributes. Verify how rule attributes reach the binary action, then confirm that custom values are supported and preserved when invoking run_binary.
