Pull Request resolved: #13795 Add 16A8W quantization support and test for the mul operation in ExecutorTorch ARM backend. This follows the pattern established for linear operations, extending int16 support to mul operations. Changes: - Add INT16 dtype validation support in op_mul.py - Add test_mul_tensor_16a8w_tosa_INT test function - Enable test_mul.py in test targets configuration The 16A8W configuration uses 16-bit activations with 8-bit weights, enabling higher precision for activations while maintaining weight efficiency. ghstack-source-id: 308923221 @exported-using-ghexport @bypass-github-export-checks @bypass-github-pytorch-ci-checks @bypass-github-executorch-ci-checks Differential Revision: [D80510628](https://our.internmc.facebook.com/intern/diff/D80510628/)
