ef95945c - feat(measure_theory/function/strongly_measurable/basic): generalize to `is_unit c` from `c ≠ 0` (#19081)

feat(measure_theory/function/strongly_measurable/basic): generalize to `is_unit c` from `c ≠ 0` (#19081) We already have this generalization for `measurable_const_smul_iff` and `ae_measurable_const_smul_iff`.
