Add SPACE_TO_DEPTH to the static_wi8_ai16 operator list in the default policy. The operator already uses the same materialize_standard_op() with SAME_AS_INPUT_SCALE constraint as RESHAPE and TRANSPOSE, which both support 16-bit activations, so no algorithm changes are needed. Add 16-bit activation test cases to both the architecture test and E2E test. The E2E test for INT16 verifies quantization succeeds without interpreter-based accuracy validation, since the LiteRT runtime kernel does not yet support INT16 for SPACE_TO_DEPTH.
