Update base for Update on "Arm backend: Add 16A8W support and test for cat operation"

Add 16A8W quantization support and test for the cat operation in ExecutorTorch ARM backend.

This follows the pattern established for linear, mul, sigmoid, tanh, slice, and view/transpose operations, extending int16 support to cat operations.

Changes:
- Add test_cat_tensor_16a8w_tosa_INT test function
- Enable test_cat.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.
