This PR adds propagation rules corresponding to the `Semiring` normalization rules introduced in #11628. The new rules apply only to non-commutative semirings, since support for them in `grind` is limited. The normalization rules introduced unexpected behavior in Mathlib because they neutralize parameters such as `one_mul`: any theorem instance associated with such a parameter is reduced to `True` by the normalizer. |
