This instance is not in Data.ENat.Basic to avoid dependency on Finsets.
We also restate some lemmas about WithTop for ENat to have versions that use Nat.cast instead
of WithTop.some.

If a ≠ 0, then right multiplication by a maps infimum to infimum.
See also ENat.iInf_mul that assumes [Nonempty ι] but does not require a ≠ 0.
