Stack from ghstack (oldest at bottom):

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.
