SI-8525 Add -Xlint:-warn-missing-interpolator

Turn off lint warnings with negating prefix, and add a lint-only
warning for the infamously nagging "Did you forget the interpolator?"

That message is made more dignified.

Without `-Xlint:false`, there is no mechanism to turn off
anonymous linters once `-Xlint` is selected.
