Rollup merge of #53412 - eddyb:stage-who, r=alexcrichton

 syntax_ext: remove leftover span_err_if_not_stage0 macro.

I believe this is the right fix for #53380, although I'm not sure what happened.
My guess is this copy of the macro was accidentally missed when others were removed?

cc @matthewjasper @varkor (please do not put this in a rollup, in case it fails)
