refactor(measure_theory/measure/mutually_singular): use ⟂ PERPENDICULAR instead of ⊥ UP TACK (#18423) The previous notation for measure_theory.measure.mutually_singular was ⊥ₘ. This changes it to ⟂ₘ, which is semantically a better character. The same change is made for measure_theory.vector_measure.mutually_singular, from ⊥ᵥ to ⟂ᵥ. Zulip
