564f9922 - [vulkan] Clamp tanh activation op input to preserve numerical stability (#73107)

[vulkan] Clamp tanh activation op input to preserve numerical stability (#73107) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/73107 It was observed that for large inputs (magnitude >= 30), the `tanh` shader would produce numerically unstable outputs when running with MoltenVK. The solution is to clamp the input with the range [-15, 15] before applying the `tanh` function.
