0ee7c943 - [mlir][vector] Tidy-up testing for to/from_elements unrolling (#158309)

[mlir][vector] Tidy-up testing for to/from_elements unrolling (#158309) 1. Remove `TestUnrollVectorToElements` and `TestUnrollVectorFromElements` test passes - these are not required. 2. Make "vector-from-elements-lowering.mlir" use TD Op for testing (for consistency "vector-to-elements-lowering.mlir" and to make sure that the TD Op, `transform.apply_patterns.vector.unroll_from_elements`, is tested). 3. Unify `CHECK` prefixes (`CHECK-UNROLL` -> `CHECK`). 4. Rename `@to_elements_1d` as `@negative_unroll_to_elements_1d`, for consistency with it's counterpart for `vector.from_elements` and to align with our testing guide (*).
