[AutoDiff] Simplify varied propagation in activity analysis. (#28191) - Remove `setVaried`. - `setVaried` has only one user and can be inlined. - Remove `setVariedAcrossArrayInitialization`. - Activity info does not change when removing special variedness propagation support for `array.uninitialized_intrinsic` applications. - Verified with array initialization activity info test cases. - Add indirect `ExpressibleByArrayLiteral` test.
